优化采区设计 合理开采工业广场煤柱

Optimization of the Design of Mining Area and to Mine Reasonably the Coal-Pillar of Mine Surface Plant

淮南矿业集团谢一矿和谢二矿并矿后，对矿井资源重新进行了划分，将原谢二矿划分为45和43两个采区，其中45采区为原谢二矿工业广场煤柱，47采区为谢二矿斜井煤柱；45采区原始设计方案影响其生产能力的充分发挥，同时也影响43采区的开采；通过对45采区设计进行优化，不仅缩短了45采区采掘接替周期，少布置685m专用回风巷，同时提前解放了47采区B4～B8煤层，保证了矿井正常接替。

After the combination of Xie - yi Coal Mine and Xie - er Coal Mine of Huainan Coal ＆ Mine Group, the mine resources have been parted renewedly. The former Xie - er Coal Mine is divided into Mining Area 45 and Mining Area 47, in which Mining Area 45 is the coal - pillar of mine surface plant and Mining Area 47 is the coal - pillar of inclined shafts in the former Xie - er Coal Mine. The original designing plan influences both the throughput of Mining Area 45 and the exploitation of Mining Area 47. Through the optimization of design of Mining Area 45, not only shorten the period of excavation replacement, and save 685m special return airway, but also emancipate the coal seam B4～B8 in Mining Area 47 ahead of schedule, as a result, it ensures the regular replacement of the new - united coal mine.
