摘要
经对康家滩煤矿1203工作面突水事故分析,指出上覆含水层突水的主要原因,通过数学物理模型模拟1201采煤工作面,得出采场应力、上覆岩层破断带距离、岩层水压传导率与工作面宽度、推进度的关系,有效指导综采工作面的设计,提出采空区充填降低水压传导、有效防治水害的新型采空区处理方法,并为地质条件类似的矿井防治水工作提出了新的思路。
By the analysis of water burst among 1203 working face in Tangjiatan mine, the paper points out the main reasons of water burst in cover water-bearing strata. Through the mathematical-physics model simulating 1201 working face, the relations among stress, distance of fracture, hydraulic pressure conductivity, and the width and driving degree of working face are achieved, which can help the design of fully-mechanized working face. A new and effective processing method of filling the mined-out areas to decrease the hydraulic pressure conductivity is presented.
