我们对华莹山中段矿区矿井中煤与瓦斯突出问题做了一些调查工作,并从中获得了一些粗浅认识,鉴于这方面工作是个新的课题,本文仅从突出点的分布、强度诸方面结合地质构造加以分析,以供参考、商讨。一、突出分布的构造部位突出是煤矿井采掘中发生在煤层-地质体里的一种危害极大、影响极坏的动力现象。从突出点分布位置看,大多与特定的构造形迹有关。而构造形迹展布的位置,是由构造应力的分配和岩石的力学性质决定的。因之,构造应力的方向性以及在各处的非均匀分布,便使突
We did some investigation on coal and gas outburst in the mine in the middle section of Huayingshan Mountain, and got some superficial understanding from it. In view of this work is a new subject, this article only from the distribution of salient points, the intensity of various aspects of geological Structure to be analyzed for reference and discussion. First, the prominence of the distribution of tectonic parts prominent coal mine mining occurred in the coal - geological body of a great harm, the impact of very bad dynamic phenomenon. From the location of the prominent point of view, mostly related to the specific structure traces. However, the position of structural trace distribution is determined by the distribution of tectonic stress and the mechanical properties of rock. As a result, the directionality of tectonic stress and the non-uniform distribution everywhere make the bump
