新峰一矿突水频繁,矿井安全受水害威胁严重,防治工程量大、难度高。通过对矿井构造应力展布规律、矿井边界及矿井内断层导水性等水文地质因素的分析,确定了该矿井突水类型。指出石炭系灰岩裂隙水和寒武系灰岩裂隙水是矿井的主要充水含水层,断裂构造是主要导水通道。地质构造对突水的控制在该矿主要体现在对突水点分布、富水带的划分以及隔水层阻水能力等方面。在对影响该区地质构造机理进行综合分析的基础上,根据矿区构造控水的特点,提出了采取物探和钻探相结合、进行放水试验、帷幕注浆和排供结合的治理措施。
Xinfeng mine a frequent water inrush, mine safety threatened by water hazards, prevention and treatment of large quantities, high difficulty. By analyzing the tectonic stress distribution law, the boundary of the mine and the hydrogeological factors such as the fault conductivity in the mine, the type of water inrush of the mine was confirmed. It is pointed out that the Carboniferous limestone fissure water and the Cambrian limestone fissure water are the main water-filled aquifers of the mine, and the fault structure is the main conduit. Geological structure of water inrush control in the mine is mainly reflected in the distribution of water inrush points, the division of water-rich zones and water barrier capacity and so on. Based on the comprehensive analysis of the geological tectonics that affected the area, according to the characteristics of water control in the mining area, this paper puts forward the measures of combining geophysical exploration with drilling, water discharge test, curtain grouting and row supply.
