摘要
大柳塔煤矿三不拉采区为浅埋薄基岩采区,采区所采2-2煤埋深60m左右,采区大部分区域基岩厚度在10m以下,极薄区域仅3m左右,采区内条件复杂。大柳塔煤矿积极研究不同采区布置方案,通过比较分析,选择最佳方案,从而保证了采区的快速掘进及安全高效开采,为浅埋极薄基岩采区工作面布置提供了经验及借鉴。
Sanbula mining area of Daliuta Coal Mine is of shallow thin bedrock and the 2-2 coal seam is of 60 me- ters buried depth. Bedrock thickness in most of the mining area is below 10 meters and the extremely thin area is just about 3 meters. Condition of the mining area is complicated and different layout schemes in the mining area are studied. By compared with the schemes, the best scheme is selected, which ensures rapid excavation and safety and high efficient coal mining in the mining area and provides some experience for workface layout in mining area of shallow thin bedrock.
