摘　　要：为了获得陈四楼煤田合理开采的临界深度,采用回采巷道的矿压现场观测以及深部开采数值模拟两种实验方法,由现场观测得到的矿压数据分析得出了600 m为深部开采临界深度,并与数值模拟分析所得结果相吻合。研究结果表明,当开采深度达到600 m以上时,陈四楼煤矿就进入到深部开采阶段。In order to determine the critical depth of reasonable exploitation in Chensilou coal mine, this paper provides two ex- perimental ways which are mine pressure filed observation of mining roadway and deep mining numerical simulation. Through analyzing the mine pressure data obtained by filed observation, it is concluded that the deep mining critical depth is 600 m, which is almost equal to the result obtained by numerical simulation. The result of study shows that Chensilou coal mine will be in deep mining stage when the mining depth is above 600 m.
