平煤十矿突出分带特征研究

Study on Zoning Characteristics of Coal and Gas Outburst in Pingdingshan No. 10 Mine

为研究煤与瓦斯突出的分带性,利用瓦斯地质单元划分、地应力分析、各地质因素分区对比分析的方法,阐述了该矿瓦斯地质特征,分析了突出分布规律,论述了多因素对突出分带性的影响,以及地应力的分带特征。结果表明:各煤组层突出发生的具有明显的分带性,突出在郭庄背斜北东翼成条带状分布,郭庄背斜北东翼为构造应力集中带;煤层厚度、煤层倾角、构造煤等因素的分区性差异都是褶皱各部位构造应力不均匀性和分带性的结果。

In order to investigate the zonation of coal and gas outburst, the method of gas geological units division, tectonic stress analy- sis, comparison analysis of geological factors were used to discuss this problem. Besides, gas geological characteristic was elaborated, the distribution regularity of outburst was discoursed, multiple geological factors which control the zonation of outburst was analyzed. The results show that the coal seams had an obvious zonation of outburst. It is concluded that outburst has a zonation in northeast wing of Guozhuang anticline and the stress is the most concentrated area. The partitions differences of geological factors such as coal thick- ness, inclination angle of coal seam, tectonic coal and other factors are the reasons of tectonic stress inhomogeneity in different part of folds.
