背斜构造裂隙场发育规律模拟试验研究

Simulation Test Study on Crack Field Development Law of Anticline Structure

在总结煤矿井下发生突水、煤与瓦斯突出等严重灾害事故后,可知煤系地层中存在的大量裂隙为突水和瓦斯提供了储存和流通通道。为了更好地治理煤矿井下突水,做好瓦斯灾害防治,通过采用理论分析结合相似模拟试验的方法,研究了背斜构造形成的过程中煤系地层中裂隙发育延伸和裂隙的分布规律。研究结果为受背斜构造和承压含水层影响煤层的防治水提供了一定的理论指导,也为矿井深部开采防治水等工程中实际问题的解决提供了借鉴。

On the basis of summing up the serious disaster accidents such as water inrush,coal and gas outburst in coal mines,it can be seen that a large number of cracks in the coal mesure strata provide storage and circulation channels for water inrush and gas.In order to better solve the problem of underground water inrush in coal mines,do a good job in gas disaster prevention and control,through the use of theoretical analysis and combined with similar simulation test methods,the development and distribution of cracks in coal mesure strata during the formation of anticline structure were studied.The research results provide some theoretical guidance for coal seam water control which is affected by anticline structure and confined aquifer,and also provide reference for solving practical problems in deep mining water control engineering.
