摘要
论文总结了开滦矿区唐山煤矿矿井冲击地压发生的一般规律,将冲击地压的影响因素按照力源因素进行了系统分析,指出构造应力和构造应力大是发生冲击地压的重要因素,在工作面开采过程中坚硬顶板断裂是发生冲击地压的主导因素。
The paper summarized the general law of the pressure bump occurred in Tangshan mines of Kailuan Mining Area. The dynamic sources factors were systematically analyzed with the influence factors of the pressure bump. The paper pointed out that the structural stress and high structural stress were the main factors to occur the pressure bump. During the mining process of the coal mining face, the breaking of the medium hard roof was the main factor to occur the pressure bump.
