摘要
煤矿瓦斯赋存构造逐级控制理论认为,瓦斯的分布特征及其赋存状态受地质构造的影响较大,并且呈现由大到小的逐级控制,即板块构造控制着区域地质构造,矿区和煤矿又受制于区域构造的控制。以淮南煤田朱集西矿为例,从地质的角度分析认为,淮南煤田的构造展布受区域地质构造控制,淮南煤田的构造特征进而影响着朱集西井田构造特征。此外,通过对地质勘探期间朱集西煤矿的瓦斯资料进行分析研究并以11-2煤层为例划分了3个独立的瓦斯地质单元,认为瓦斯地质单元Ⅰ和Ⅲ为低瓦斯区、瓦斯地质单元Ⅱ为深部瓦斯富集区。
Coal mine gas occurrence cascade structure control theory,the characteristics of distribution of gas and occurrence status is strongly influenced by geological structure,and present the control step by step from big to small,the plate tectonic controls the regional geological structure,and coal mining area is under the control of the control of regional structure. Zhu set west mine in huainan coalfield as an example,from the Angle of geological analysis of huainan coalfield structure distribution are controlled by regional geological structure,the structural characteristics of huainan coalfield,in turn,affects the tectonic characteristics of the west field zhu set.In addition,based on the geological exploration during zhu set west coal mine gas data analysis as a case study of 11- 2 coal seam gas geological unit,divided into three independent think gas geological unitⅠandⅢfor low gas zone,the gas geological unitⅡfor deep gas enrichment region.
