陈蛮庄煤矿3602工作面突水分析及防治水措施

Analysis and Water Prevention and Control Measures of Water Inrush in the 3602 Working Face of Chenmanzhuang Coal Mine

3602工作面开采过程中出现突水,为了分析工作面突水原因,通过对近露头煤柱留设情况及底板三灰岩层富水情况分析,并基于矿山压力理论,得出工作面涌水增加是停采导致底板破坏深度增大引起的。根据当前出水情况,提出了底板注浆加固、留设防水煤柱、疏水降压以及井下水害探测等防治水措施,确保工作面安全开采。

During the mining process of the 3602 working face,water inrush occurred.In order to analyze the causes of water inrush in the working face,by analyzing the retention situation of coal pillars near the outcrop and the water rich situation of the floor three limestone layers,and based on the theory of mine pressure,it is concluded that the increase in water inrush in the working face is caused by the increase in the depth of the floor failure caused by the cessation of mining.According to the current water outflow situation,measures for water prevention and control are proposed,such as floor grouting reinforcement,retaining waterproof coal pillars,water drainage and pressure reduction,underground water hazard detection,and so on to ensure safe mining of the working face.
