工业广场煤柱开采地表变形规律研究

The study of Mining Feasible Scheme about Part of Work Faces Mining under Mine Industry Square Pillar

针对工作面进入工业广场煤柱下回采设计了12个开采方案,采用概率积分法对各方案地表变形情况进行了理论计算和分析,得出了地表各处的变形预计结果。根据预测结果,从中选取了最优的开采方案,既保证了地面建筑物的安全。

mining programmes were designed for multi-working-face mining under the pillar of mine industry square. By using probability integral method, the surface distortions were calculated and forcasting result was given. According to the result of predicting , the optimum mining plan were chosen which not only guaranteed the security of building on the ground but also liberated coal resources as much an possible.
