煤田开发与开采过程中,经常遇到与地质构造有关的一系列生产地质问题,如深部找煤、井下断失煤层的寻找、顶板管理、矿井突水、瓦斯突出、火成岩分布等等。本煤田开采过程中,上述这些问题当中的大部分都有所表现。因此,本文试图运用地质力学观点,对本煤田的地质构造初步进行一次力学分析,找出一些规律,以便促进本煤田各个局部地段生产地质问题的解决。一、本区地质构造形迹的展布峰峰石炭二迭纪煤田位于太行山中段,属新华夏系的一部分。为一北北东向的狭长隆起地带。南北长约40公里,东西宽20多公里。地层倾斜度小,褶皱不太发育。局部地方,如鼓
During the process of coalfield development and mining, a series of production geological problems related to geological structure are often encountered, such as looking for coal in deep area, searching for coal seam lost in underground mine, roof management, water inrush in mine, gas outburst, distribution of igneous rock and so on. During the mining process in the coalfield, most of these problems have been manifested. Therefore, this paper attempts to use the geomechanical point of view, a preliminary geological analysis of the coalfield mechanics, to find out some laws in order to promote the production of geological problems in various parts of the coalfield. First, the distribution of the geological structure of the peak Fenghuang Carboniferous Permian coal field is located in the middle of the Taihang Mountains, a part of the new China and the United States. For a long north-east uplift strip. About 40 km north-south, east-west width of more than 20 km. Stratum inclination is small, fold less developed. Local places, such as drums
