【摘要】：本文研究了豫西陕渑煤田主要含水层和其补径排条件，收集了已发生的矿井水害资料，指出：矿井现生产采区的主要水害类型为顶板砂岩水和底板灰岩水，重点是底板奥陶系灰岩溶裂隙水。应用“三图－双预测”法对顶板砂岩水的突水条件进行了危险性分区和涌水量预算，应用脆弱性指数法对底板太原组灰岩与奥陶系灰岩含水层的突水危险性分别进行了评价和危险性分区，指出：由于长期疏排（泄），顶板砂岩水和底板太原组薄层灰岩水水位大幅下降，储量不足，，对矿井正常生产影响有限；矿井防治水工作的重点和难点在于预防奥灰含水层突水。根据奥灰突水危险性分区，提出了加强管理、健全水位动态观测系统、扩大矿井排水能力、综合物探查异、注浆改造底板、排用结合等对策与建议。
[Abstract]:This paper studies the main aquifers and the drainage conditions of the Shanxi Mian coal field in the west of Henan Province. The water damage data of the mine have been collected. It is pointed out that the main water damage types of the mine production area are the roof sandstone water and the bottom limestone water, and the key is the limestone karst fissure water in the floor Ordovician system. The process of "three map double prediction" is applied to the water of the roof sandstone. The water conditions carried out the hazard zoning and the budget of water inflow. The water inrush hazard of the Taiyuan limestone and Ordovician limestone aquifers in the floor was evaluated and the risk zoning respectively by the vulnerability index method. It was pointed out that the water level of the top plate sandstone water and the floor Taiyuan formation of the thin layer limestone water decreased greatly and the reserves were insufficient because of the long-term sparse drainage (discharge). The key and difficult point of mine water prevention and control is to prevent the water inrush from the aquifers in the coal mine. According to the zoning of the arcane ash water inrush, the countermeasures and suggestions are put forward to strengthen the management, improve the dynamic observation system of the water level, expand the drainage capacity of the mine, comprehensive geophysical prospecting, grouting to rebuild the floor, and the combination of drainage and use.
