摘要：

为提高矿井水害防治效果,降低矿山安全隐患,首先,以乌兰木伦2^-2煤二盘区首采面为研究对象,分析矿区水文地质状况,探究导水裂隙带贯通情况对水害的影响;然后,采取物探、钻探相结合的方式开展探放水现场试验,预测评估工作面突水量,并通过工作面水量计算设计合理的排水系统;最后,提出回采工作面预留保护煤柱和局部区域顶板强排疏放等消除工作面水害隐患的措施。结果表明:2^-2煤回采过程中导水裂隙带贯通上覆采空区,具有较大的突水危险;经物探和钻探法相结合的探放水方式后,底板突水系数最大值为0.001 MPa/m,突水可能性较小;采取局部区域顶板强排疏放可有效降低突水危险。

Abstract:

In order to improve the prevention and control effect of mine water disaster and reduce the hidden danger of mine safety, firstly, taking the first mining face of panel Ⅱ of Ulan Mulun 2^-2 coal mine as the research object, the hydrogeological conditions of the mining area were analyzed, and the influence of the penetration of water diversion fracture zone on water disaster was explored. Then, the field test of water exploration and drainage was carried out by combining geophysical exploration and drilling to predict and evaluate the water inrush of the working face, and a reasonable drainage system was designed through the calculation of the water amount of the working face. Finally, some measures were put forward to eliminate the hidden danger of water disaster in the working face, such as reserving protective coal pillars and forced drainage of the local roof. The results show that the water-conducting fracture zone runs through the overlying goaf during the mining process of 2^-2 coal, which has a great water inrush risk. After the combination of geophysical exploration and drilling method, the maximum water inrush coefficient of the bottom plate is 0.001 MPa/m, and the possibility of water inrush is slight. The water inrush risk can be effectively reduced by strong drainage of the local roof.
