摘　　要：煤层厚度稳定性是影响采煤方法、布局及采煤效益的重要因素之一。根据钻孔资料和矿井生产资料,对潘一矿及谢-李矿深部井13-1煤层厚度稳定性进行分析。结果表明,研究区13-1煤层厚度稳定性随深度加深而趋于稳定。并运用煤岩力学性质在浅部与深部的差异对这一现象进行解释。The stability of the coal seam thickness is one of the most important factors in affecting the method,the distribution and the benefit of excavating coal.According to the borehole and production data,this article analyses the same coal seam：13-1 of panyi mine and wangfenggang mine.The results show that the stability of the coal seam 13-1 in investigation is positive correlated to depth,besides,by using the upper and lower coal seam differences in mechanical property of the coal petrology,this phenomenon can be well explained.
