东滩矿63_上04工作面突水分析
|
摘要
东滩矿63_上04是六采区首采工作面,位于C2向斜轴部,钻探没有探出富水,回采过程中发生了小型突水,通过分析其所处的水文地质环境和取得的监测检验数据,确定了突水水源和涌水通道。提出,防排水系统是工作面的必备条件,利用工作面的有利条件最大可能地完善排水设施,采区首采工作面,特别是采区的向斜轴处的工作面,须合理做好防排大水的各项准备工作。
Upper 6304 working face of Dongtan Mine was the first mining face of sixth panel that located in the axial part of C2 synclinal, and drilling results showed there was no water-rich zone, but little water inrush accident occurred during mining process. Through analyzing the locating hydrogeological environment and achieved monitoring and testing data, the water inrush source and channels were determined, and it put forward that the water preventing and drainage project was the essential condition of working face, and it was necessary to complete the drainage facility at all possible by using the advantages of working face, and to prepare rational proposals for large water inrush prevention and drainage in the first mining face, especially for the working face located in the axial part of syncline.
