摘要
利用钻孔测井曲线,结合井巷工程揭露情况和工作面坑透,对潘三矿构造软煤发育和分布进行了综合分析,查明了潘三矿C13-1煤层构造软煤的分布特征。研究表明,南北向推覆作用形成的褶皱顺层滑动对该煤层构造软煤的发育和分布起着主要控制作用,断层及其与褶皱的叠加是煤层局部构造软煤加厚的主要原因。这些认识为潘三矿突出危险性区域划分奠定了基础。
Utilizing borehole logging curves combined with the data obtained from the under- ground workings exposing the coal seam and the use of underground electromagnetic wave perra- diator, a comprehensive analysis of the development and distribution of tectonic soft coal in Pansan Coal Mine is carried out. The results of study show that coal bedding-slip fold caused by north-south overthrusting plays a major control role in the tectonic soft coal distribution and de- velopment. The main reason why local tectonic soft coal becomes thick is the fault structure and the overlapping structure where fault and fold come together. This understanding provides a good basis for marking the outburst hazard zones in Pansan Coal Mine.
