| 摘 要： | 为研究浅埋煤层走向煤柱对近距离下部煤层工作面开采时支承压力的影响,运用FLAC3D软件对大柳塔煤矿21306工作面进行数值模拟。结果表明:当煤层埋藏较浅,对工作面开采带来的影响不大,但如果煤层间距变小或随着采深加大,影响的程度则会加大。

| Abstract: | For a research on the impact of coal pillars along strike in shallow coal seams on the abutment pressure encountered during coal mining in contiguous lower coal seams,FLAC3D software is used in a numerical simulation of #21306 coal face of Daliuta Coal Mine.Results indicate that due to the shallow depth of the coal seam in question,the impact is not very significant on coal mining operation in the face.However,with coal seam interval becoming smaller or in case mining depth increases,the impact intensifies. |
