The Czech Mining Authority provides pursuant to § 22 paragraph 6 and § 30 paragraph 2 of Act No. 61 / 1988 Coll., on Mining Activities, Explosives and State Mining Administration, as amended by Act No. 376 / 2007 Coll. and Act No. 451 / 2016 Coll.:
BASIC PROVISIONS
Subject matter
This decree provides
(a) technical requirements for the location and execution of structures and areas intended for the research, development, manufacture, testing, destruction, disposal or processing of explosives (1), including production, laboratory, delaboration or destruction of ammunition or munition2) or manufacture of pyrotechnic articles (3), where explosives are handled in such activities; and
(b) explosive hazard classes.
Basic concepts
For the purposes of this decree:
(a) the building or area intended for the research, development, manufacture, testing, destruction, disposal or processing of explosives;
(b) by lining up the maximum authorised quantity of explosive,
(c) the safety distance of the smallest permissible distance between the object and the surrounding construction or area which this decree grants protection (hereinafter referred to as "endangered construction");
(d) the safety circuit of the border which defines the degree of damage to the endangered building previously chosen;
(e) the safety zone of the area defined by the safety circuits;
(f) a heavy wall with a pendulum wall placed in bearings so that the effect of the pressure wave can be deflected (turn),
(g) a protective wall of a structure of solid materials having the same function as a protective wall;
(h) the supporting wall of the structure, constructed on the inside or outside of the protective wall, ensuring its stability;
(i) the exhaust surface of the part of the object (wall or roof) which allows for a rapid drop of pressure in the explosion inside the object;
(j) an exhaust roof with reduced weight of roof cover (without roof) made of light, easy to crush material for objects dangerous to explosive explosion or to fire flammable vapours;
(k) storage storage space (container, etc.) intended for the storage of explosives or explosive waste during shift;
(l) a protective bead, designed to protect the surrounding area against the effects of the explosion;
(m) a separate wall of protection which is not directly linked to other protective bodies providing the same object,
n) a common wall protection wall separating the objects of one building complex,
o) closed wall with tunnel passages surrounding the object from all sides,
(p) a set of manufactures of several directly related objects, considered as one whole in terms of linings and safety distances to the nearest vulnerable buildings,
(q) an armored door door with a pressure wave resistance of at least that of the building walls;

EXPLOSION, LABORATORY, TEST, DEVELOPMENT WORK AND INSTALLATIONS
Conditions for construction
(1) Objects must comply with general technical requirements, (4) unless otherwise provided for in this Decree.
(2) Natural and legal persons shall, in the activities covered by this Decree (hereinafter referred to as the "organisation"), provide for the premises of the establishment of the fence or otherwise ensure against the entry of unauthorised persons. The distance of objects dangerous by explosion or explosive fire from the fencing of the plant shall be determined in the project documentation taking into account local conditions, threats and construction design.
(3) The fence must not prevent the escape of persons from the building. The entrance to this area must be controlled.
(4) The area 5 m wide from fencing must not be afforested.
Explosive and object hazard classes
(1) Explosives are classified in the hazard classes and groups referred to in Annex 1 to the Explosive Storage Regulation (5) according to the behaviour of the explosive transformation.
(2) The hazard class of an object is determined by the class and hazard group of the explosive for which the object is intended and by the highest degree of hazard of the operations carried out therein. The classification of the most important production sites in terms of the threat to the environment is set out in Annex 2, which is part of this Decree.
Determination of safety distances
(1) The security distance is determined in accordance with Annex 3 to this Decree.
(2) When calculating the safety distance, all explosives, with the exception of explosives 1.4S in accordance with Annex A to the Europe Agreement on the International Carriage of Dangerous Goods by Road (ADR) 6, shall be included in the linings. If there are different hazard classes in the explosive object, the safety distances for the highest class and hazard group explosive shall be determined, taking into account the overall lining. If the part of the building is separated from the others in a way that prevents the escalation of the effects due to the initiation of explosives in other parts, partial lining of the part of the building may be used to determine the safety distance; the requirement is deemed to be met if the part of the building is separated from the others in a way that prevents the transfer of explosion and fire. When determining the safety distance between two mutually threatening objects, the safety distance shall be determined for each object separately, the larger of which being decisive. The safety distance shall be calculated from the wall or edge of the threatening space.
(3) For the determination of the safety distance:
(a) if the object is partially oiled, then in the direction of the open pages the safety distance is calculated as for the object not oiled,
(b) if two adjacent objects are turned towards each other by open sides, the distances between them shall be determined as being for objects without valleys;
c) if the free side of the bunker object is protected by a bead, this object is considered to be ovaled,
d) if two objects have a common wall, each one is considered to be an object with one wall,
(e) for bunker-type constructions placed in a common powder, each of them shall be considered to be ovaled;
(f) where the manufacture of explosives is carried out in buildings which are directly adjacent to it, where the transfer of the explosion from one object to another is not prevented, such objects shall be considered as a set of production sites; safety distances shall be calculated according to the total linings of the production set.
(4) Where ammunition, ammunition or pyrotechnic articles are also present in the premises within their production, laboratory or delaboration, paragraphs 1 to 3 and Section 4 shall apply mutatis mutandis.
(5) Where a building intended for ammunition, ammunition or pyrotechnic articles is at risk of construction, paragraphs 1 to 3 and Section 4 shall apply mutatis mutandis.
Protective bays
(1) Ambient of hazard class objects And it protects against the effects of blast by protective walls, protective walls, exhaust construction, tilting walls, forestation, etc. A natural obstacle, such as a roof, hill, rock, a grown forest area at least 15 m wide, can replace a protective wall, a protective wall if it is high enough. The transparency of forest land in this case shall not exceed 30% in the winter period and its assessment shall be documented by the organisation by calculation or photographic. Forestry must be at least 5 m away from the objects
(2) If the calculation of the safety distance referred to in Section 5 results in an obligation to set up a protective wall, it shall be established in all directions of potential threat.
(3) Only non-flammable and compacted material can be used to build protective bays. If the protective wall is made of stoneware, a layer of sorted material with a thickness of at least 1 m with a grain diameter of up to 16 mm shall be used on its inside. The surface of the protective wall shall be secured against erosion.
(4) The roof ledge of the building must not exceed the crown of the protective wall; at the object with one-sided inclination of the roof this applies to the roof ledge of the lower side of the roof. However, it is necessary that the crown of the protective wall exceeds by at least 0,5 m the upper level of the explosives processed. The inner slope of the protective wall may have a slope of not more than 40 ° and a crown width of not less than 0,5 m. The profile of the protective wall shall be demonstrated by calculation of stability including the seating of the wall body and its pushing into the ground.
(5) If one of the protective bays is not connected to other protective bays, it shall extend beyond the lateral edges of the other bays by at least 0,5 m. A detached wall can be replaced with an equally high protective wall. The protective wall may have the end of the side part with a supporting wall up to a height of not more than two thirds of the protective wall.
(6) The distance of the heel of the closed wall to the wall of the building is not more than 3 m and the distance of the heel of the separated wall from the wall of the building is not more than 5 m. The gap between the heel of the protective wall and the wall of the building is adjusted by sanding, paving or concrete, without grass or vegetation. Along the heel of the protective wall, a gutter is established to drain water.
(7) The inner slope of the protective wall need not comply with the inclination laid down in paragraph 4 at its full length if a vertical supporting wall is part of it; However, this shall not exceed half the height of the protective wall. No device, explosive storage and storage facilities and explosive waste shall be placed in the inner slope of the protective wall.
(8) If the risk of explosion in the part of the object cannot be excluded, it must be ensured that the reflection of the pressure wave is reduced to adjacent workplaces.
(9) A protective wall may be used instead of a protective wall. The distance of the protective wall from the walls of the object shall not be less than 1 m and shall not exceed 5 m.
(10) Passages in the protective wall shall be established either by interrupting the protective wall or as tunnels. They are set up as close as possible to the escape route from the building, they are at least 1,5 m wide with a gradient of 8o, arched or broken so that any line through them intersects their wall protected by a protective valve. In the event of failure to comply with this condition, a further protective wall or a protective wall shall be established at a distance of 1 to 4 m from the outer heel of the protective wall against the mouth of the passage, overlapping the tunnel mouth by at least 1,5 m in all directions or of the same height as the cut-off wall and with a crown exceeding the crown of the cut-off wall by at least 0,5 m.
(11) The tunnel passage is set at least 2,1 m high with lighting without any outlet with walls and ceiling made of reinforced concrete or other durable material.
