雅店煤矿在开采过程中,含水层情况和裂隙发育对涌水量和煤层回采造成的影响十分复杂,回采活动可能会因洛河组含水层而造成涌水突增,从而制约回采活动。针对开采中主要存在的洛河组含水层富水性不均一、导水裂隙带发育高度大、易形成脉冲式涌水和采空区积水问题,主要采用自然疏排的方式进行顶板洛河组含水层水害防治。提出了采用洛河组含水层水位分层监测技术、涌水量预测技术、含水层水害综合防控技术、工作面开采参数优化和矿井排水系统优化等技术措施主动防控巨厚洛河组含水层水害。该技术体系的建立对于雅店煤矿巨厚含水层下煤层开采防治水的安全保障具有重大意义。

effect on the water inrush and coal seam mining, and the mining activity may cause the abrupt increase of water inrush in theaquifers of Luohe formation, thus the mining activity is restricted. In response to the main problems in mining, such as theuneven water abundance of aquifers, the high development height of water conducting fracture zones, and the tendency toform pulse water inrush and goaf water accumulation, it is proposed to adopt technical measures such as layered monitoringtechnology for the water level of the Luohe Formation aquifer, prediction technology for water inflow, comprehensive preven-tion and control technology for aquifer water hazards, optimization of mining parameters on the working face, and optimizationof mine drainage system to actively prevent and control the water hazards of the thick Luohe Formation aquifer. The estab-lishment of this technical system is of great significance for ensuring the safety of water prevention and control in coal seammining under the thick aquifer of Yadian Coal Mine.
