以具有“深部大倾角”特性的开滦赵各庄矿为研究对象,在现场调研和实测的基础上,通过物理模拟对上覆煤岩裂隙场规律进行研究。研究的思路和方法不同于以往随工作面推进方向进行的动态裂隙场规律研究,而是沿倾向方向对其研究,对以往裂隙场发展规律进行了验证和完善,并得出了在采动影响下深部大倾角裂隙场发展演化的一些特有的规律,为瓦斯抽放和煤矿安全生产提供一定的理论支持和指导。
Taking Zhaogezhuang Kailuan mine with “deep major dip angle” as the research object, based on field investigation and actual measurement, the law of overlying coal rock fracture field was studied by physical simulation. The research ideas and methods are different from the previous research on the dynamic fracture field law with the advance of working face, but the research on the direction of the dip is carried out. The development rules of the past fracture field are verified and perfected. Some special laws governing the development and evolution of deep-dip and large-angle fracture fields are provided to provide some theoretical support and guidance for gas drainage and coal mine safety production.
