The pitch of 9^# and 10^# thin coal seams of Huozhou Coal Electricity Xinzhi Coal Mine of Shanxi Coking Coal Group is only 1.71m, which is taken as the engineering background of our study of the close distance coal seams.Some relatively mature theory on the close-distance seams is used to calculate and analyze the alternate distance of 9^# seam and 10^# seam combination mining face. The FLAC3D software is used to simulate the stresses in 10^# seam and 9^# seam under the combination mining with different alternate distances. The result shows that, during the combination mining of Xinzhi Coal Mine 10^# seam and 9^# seam, the reasonable alternate distance should not be less than 35 m. The research results show how to improve the coal resource recovery ratio, and ensure the safe and efficient production of coal enterprises., authors=YANG Yanguo, WANG Chunlong, HUANG Xu,

articleAbstract=近距离煤层在开采过程中,存在着上下分层间相互影响、巷道布置与支护困难、工作面接替紧张、生产效率偏低等问题,一直困扰着煤矿的安全高效生产。山西焦煤集团霍州煤电辛置煤矿9^#薄煤层和10^#煤层层间距仅为1.71m,以此作为工程背景进行近距离煤层同采方案研究。根据目前研究近距离煤层开采较为成熟的“稳压区理论”与“减压区理论”,对辛置煤矿9^#、10^#煤层两同采工作面错距进行计算分析;运用FLAC3D软件对9^#、10^#煤层两个工作面同采不同错距条件下所产生的应力效果进行数值模拟。研究结果表明,辛置煤矿10^#煤层与9^#煤层同采过程中工作面的合理错距不应小于35m。研究解决了辛置煤矿工作面接替紧张、资源浪费严重等问题。,
