DECLARATION
Czech Mining Office
of 28 January 2000
amending the Order of the Czech Mining Office No. 52 / 1997 Coll., laying down requirements to ensure safety and health at work and safety of operations in the disposal of main mining works
According to § 6 (6) (a) of Act No. 61 / 1988 Coll., on Mining Activities, Explosives and State Mining Administration, the Czech Mining Authority provides:
Decree No. 52 / 1997 Coll., laying down requirements to ensure safety and health at work and safety of operations in the disposal of main mining works, is amended as follows:
1. in Paragraph 2 (d):
"(d) the main mine work - the mine work resulting in the surface. The main mine parts are exploratory mining works (shafts, chimneys), openings (pits, stalls), ventilation, drainage, mining and rescue wells. The main mine are not search and reconnaissance wells."
2. in Article 2 (f):
"(f) inertization - creating a non-explosive environment in a liquidated mine,"
3. in § 2 (h):
"(h) the safety area - the area on the surface in the immediate vicinity of the mouth of the main mine in which the rising mining air may endanger the life or health of persons."
4. in Article 3 (2), points (c) and (g) are deleted;
5. in Article 3 (2) (l):
"(l) for fluent and coal mines, an assessment of the possible ways of the methane output to the surface, an evaluation of the gas intensity and measures to prevent uncontrolled gas leakage to the surface,";
6. in Paragraph 3 (2) (m):
"(m) the method and calculation of ventilation, or the method of inert the main mine in its liquidation (§ 14a),"
7. Paragraph 5 (1) reads as follows:
"(1) The pit is disposed of by its complete filling with reinforced filling material. If the nature of the pit so permits, unreinforced filling material may be used on the basis of the permission of the Mining Authority; the authorisation shall include measures to ensure safety in terms of the stability of the pit and its surroundings. ';
At the same time, footnote 6 is deleted and the reference is made in Section 5 (2).
8. Paragraph 5 (2) reads as follows:
"(2) The method of disposal of the other main mining works shall be determined by the documentation (§ 3). '

10. in Article 7 (3), the words "or flooded" shall be inserted after the words "watered down."
11. in Article 7, paragraphs 4 and 5 are deleted;
12.
Brackets
The structure of the supporting barrier, its location, the method of ensuring stability of the column of unreinforced filling material and the resistance to load by hydrostatic pressure shall be determined by the documentation. ';
13. Article 9, including the title, shall be deleted;
14. Paragraph 10 (6) reads:
"(6) The closure of the pubic hair shall be marked in a permanent manner. The designation shall include the name of the pit and mine, its light diameter and depth, the year of commencement of the pit dig and the year of end of its disposal, an indication of the method of disposal of the pit, the type of filling material, the size of the safety zone and the warning of potential gas hazards. It shall also be marked with the mouth of the destroyed stol. ';
15. In Article 10, the following paragraph 7 is added:
"(7) The gases migrating between the rock mass and the pit wall must be carried away by a exhaust chimney. The exhaust chimney shall be equipped with a closing fittings and shall allow sampling and connection to the exhaust system or equipment. ';
16. in Article 11 (1):
"(1) The safety zone shall be established on the surface around the liquidated main mine. The minimum size of the safety zone defined in the documentation (Section 3) for pits shall exceed their outer circumference by at least 20 m. The size of the safety zone in the pit shall be increased accordingly, taking into account the state and manner of its disposal, the mining, geological, hydrogeological and geotechnology situation in the immediate vicinity of the destroyed pit. The size of the safety zone for other main mining works shall be determined taking into account the nature of the main mining work, the mining, geological, hydrogeological and geometrical situation surrounding it. ';
17. in Article 11 (2), the words "at all heights" shall be deleted;
18. in Paragraph 11 (3), including footnote 8a, read:
"(3) The safety zone shall be marked in the metering and geological documentation.
8a) § 14 (1) of Act No. 61 / 1988 Coll. '.
19. Paragraph 11 (4), including footnote 9, reads:
"(4) The organisation shall submit a proposal to the construction office for a decision on the construction closure in the safety zone, on the manner and extent of the fencing and designation of the liquidated main mine, and, where appropriate, on any other change in the use of this territory. The organisation shall also notify the zoning authority of the determination of the safety zone and the submission of the proposal to the construction office. A copy of the decision authorising the liquidation of the main mine will be sent by the district mining office and the zoning authority.
9) Act No. 50 / 1976 Coll., as amended. Decree No. 132 / 1998 Coll., implementing certain provisions of the Building Act. '
20. Paragraph 12 (1) reads:
"(1) A security area shall be established around its mouth when the main mine is destroyed. The safety area shall be demarcated on a flat basis at least within the scope of the safety zone. Its height shall be determined by the organisation in the documentation in such a way as to avoid the possible adverse effects of mining gases. 10)."
