淮北矿区位于华北煤田东南缘，属华北型煤田，临涣、涡阳矿区位于该矿区南西块段。该区开采的二叠系下统山西组10煤层受下伏太原组灰岩水突水威胁。通过研究淮北临涣、涡阳矿区构造地质及太灰水文地质条件，界定了太灰含水层高承压弱富水的水文地质特征。经统计分析淮北、肥城等矿区200多个突水点突水系数与隔水层厚度、含水层钻孔单位涌水量之间的关系，提出了Ts－M、Ts－q承压水体上开采突水系数安全评价方法，解决了煤矿深部承压水体上开采安全评价依据不充分、防治水工程量大等问题。
淮北礦區位于華北煤田東南緣，屬華北型煤田，臨渙、渦暘礦區位于該礦區南西塊段。該區開採的二疊繫下統山西組10煤層受下伏太原組灰巖水突水威脅。通過研究淮北臨渙、渦暘礦區構造地質及太灰水文地質條件，界定瞭太灰含水層高承壓弱富水的水文地質特徵。經統計分析淮北、肥城等礦區200多箇突水點突水繫數與隔水層厚度、含水層鑽孔單位湧水量之間的關繫，提齣瞭Ts－M、Ts－q承壓水體上開採突水繫數安全評價方法，解決瞭煤礦深部承壓水體上開採安全評價依據不充分、防治水工程量大等問題。

Huaibei Mining Area is located in the southeast margin of the North China Coalfield , belongs to the North China type coal field .Linhuan Mining Area and Guoyang Mining Area are located in the southwest block . In the mining area, No.10 coal seam being mined belongs to Shanxi formation of Lower Permian formation , which is threatened by water inrush from the underlying limestone of Taiyuan formation .On the basis of study of geological structure and hydrogeological conditions in Linhuan and Guoyang Ming Areas , the hydrogeological characteristics such as high pressure and weak water yield of limestone aquifer were determined .Based on the a-nalysis of the relationship among water inrush coefficient , water-resisting floor thickness and specific capacity in 200 water inrush spots in Huaibei and Feicheng Mining Areas , the water inrush coefficient safety assessment methods of Ts-M and Ts-q for mining on confined water were proposed , which resolve the problems of the in-sufficiency of safety assessment basis and large engineering working for water prevention and control in mining on confined water .
