摘要
对龙固煤矿东三采区西部焦化厂二期工程下8煤层条带开采进行研究,采用地表移动变形预测模型对8煤层开采引起的地表移动变形进行预计,并对开采方案进行优化。实践表明:所选开采方案合理,保证了地面建筑物的安全,提高了煤炭资源的回收率,可供其它煤层的开采提供借鉴。
The paper makes a pre--calculation of mining--induced surface movement and deformation with pre dictive model in strip mining at No. 8 coal seam under buildings and optimizes the mining scheme, which has en sured the safety of surface building and improved the coal recovery rate.
