摘要
针对某矿巷道群周围保护煤柱过大的问题,采用数值模拟和现场监测的方法对保护煤柱的可采宽度进行了研究。结果表明,保护煤柱在巷道群不受影响的情况下还可继续开采,并根据研究结果提出了合理的保护煤柱宽度。
According to the problem of excessive protective coal pillar around group of tunnels in a certain coal mine,the recoverable coal wedge width is researched by numerical simulation and field engineering monitoring.The results indicated that the protective coal pillar may go on mining and the group of tunnels can't be damaged and the appropriate coal wedge width is putted forward according to the study results.
