针对兖矿集团安源煤矿采用常规岩移影响带的计算方法导致的煤柱尺寸留设过大、资源浪费过大的情况,基于4205和4206工作面的具体情况,采用煤柱屈服公式计算煤柱留设尺寸,通过与常规计算对比分析并用数值模拟进行验证,结果表明屈服公式计算尺寸更加合理且节约资源。屈服计算法可为安源煤矿其他工作面煤柱宽度留设提供一定参考依据。
For Anyang Coal Mine of Yankuang Group, the coal pillar size is too large and the waste of resources is too large due to the calculation method of the conventional rock drift affecting belt. Based on the concrete conditions of 4205 and 4206 working face, coal pillar yield formula is used to calculate coal The size of the column was set aside, and compared with the conventional calculation and numerical simulation, the results showed that the yield formula was more reasonable and the resource was saved. Yield calculation method for Anyuan coal mine pillar face width to provide some reference.
