摘要
为查清彬长胡家河矿井首采区域的主要煤层赋存形态以及地质构造发育情况,以便矿井设计及采掘工程提供可靠依据,对首采区域开展了三维地震勘探。得到了较好的原始资料,查明了该区域内断层16条,落差H>10 m的断层8条,落差5 m≤H<10 m的断层7条,落差H<5 m的断层1条,并解释了区内超过5 m的褶曲6个,包括4个向斜,2个背斜,同时,预测了区内4号煤层的厚度变化情况。
A 3D seismic survey was carried out in the first mining area in order to find out the distribution pattern of the main coal seams and the development of geological structures in the first mining area of Binchang Hujiahe Mine,so as to provide a reliable basis for mine design and mining engineering.Good primary data was obtained,identifying 16 faults in the area,8 faults with a drop of H>10 m,7 faults with a drop of 5 m≤H<10 m and 1 fault with a drop of H<5 m,and interpreting 6 folds exceeding 5 m in the area,including 4 diagonals and 2 backslopes,and predicting the thickness variation of coal seam 4 in the area.
