摘要:
吕梁矿区某矿山西组煤层受奥陶系灰岩含水层和太原组灰岩含水层高承压水威胁，工作面回采时发生了底板突水。为了快速、准确判别突水水源类型，分析突水原因并制定合理的治理措施，采用灰色关联度法分析水质关联度，利用弹塑性理论计算了煤层采动后底板最大破坏深度，分析了隔水层厚度及岩性组合的隔水性能。分析结果表明，煤层底板隔水层厚度平均26m，且软岩所占比例达到6218%，灰色关联度分析突水水源接近太原组灰岩水，底板最大破坏深度267m，距离煤壁224m,与实际突水点吻合，判断突水水源为太原组灰岩水
Abstract:
The coal seam of Shanxi formation has been threatened by the Ordovician limestone aquifer and Taiyuan formation limestone aquifer in Lvliang coal mine area, and water inrush has happened with coal extraction. In order to determine the source of water bursting rapidly and accurately, the reasons of water inrush were analyzed and the reasonable management measures were proposed in this paper. The water quality association was analyzed by using the gray relation analysis, and the maximum damage depth was calculated by using the theory of elasticplastic. The aquiclude thickness and performance of lithological combination were analyzed. The results showed that the average thickness of aquiclude is 26 m, and the proportion of soft rock can reach 6218%, the source of water bursting close to Taiyuan group limestone aquifer, the maximum damage depth can reach 267 m, as well as 224m from the coal wall, which accord with actual water bursting point. The source of water bursting is Taiyuan group limestone water.
