龙王沟煤矿特厚煤层上行开采可行性分析

 针对煤层的赋存条件,采用理论分析、UDEC数值模拟对特厚煤层上行开采的必要性、可行性进行论证,并确定合理的上行开采方案。研究结果表明：由于上部可采煤层赋存条件差,该矿井采用上行开采非常必要。理论计算结果表明,6号煤层采用一次采全厚整层开采会对上部煤层造成破坏,技术上不可行,可采用预采顶分层（采高6m）上行开采方案。

Feasibility analysis of upward mining in super high seam

Aiming at the coal seam occurrence conditions, the feasibility and necessity of upward mining was analyzed by theoretical analysis and UDEC numerical simulation. The upward mining program was confirmed. The results showed that it was very necessity to use the upward mining, because of the poor coal seam occurrence conditions. The full seam extraction upward mining program was not feasibility for 6 mine seam. The pre mining top slicing upward mining program was feasibility, which mining height was 6m.
