连续建筑物下压煤条带开采技术

Coal Strip Mining Technology Under Continuous Buildings

以余吾煤业齐村下压煤为实验目的,采用理论计算、地表移动、数值模拟、变形预计,对齐村下压煤条带开采采留宽度的安全范围、不同煤柱开采方案、煤柱稳定性、以及开采引起的地表沉降预测进行了分析,分析结果表明,余吾煤业村庄下压煤采用条带开采是可行的,提高了煤炭资源的采出率,延长服务年限,成功实现村庄不搬迁情况下煤炭资源的安全开采。

Taking the pressed coal in Qi village of Yuwu Coal Company as experimental purpose. The methods of theoretical calcula- tion, surface movement, numerical simulation and deformation prediction are adopted to analyze the safety range of mining and remai- ning width, different coal pillar mining plan, coal pillar stability as well as surface deformation prediction caused by mining under Qi village,it suggest that the mining under Qi village is feasible, which improves the mining rate of coal resource, prolongs the service life and realizes the safety mining of the coal resource under the case of un - removing.
