槽波地震勘探技术在煤层薄化区探查中的应用
|
摘要
新安煤田属于典型的鸡窝煤,煤层赋存不稳定,给安全生产带来很大不便,云顶煤业在生产过程中经常遇到煤层薄化等现象。随着煤矿综合机械化水平的提高,采煤工作面内部的煤层薄化带对煤矿安全生产影响越来越大。为了探清工作面的煤层薄化范围,云顶煤业利用坑透、槽波地震勘探等多种物探技术对工作面进行了探测分析,查出工作面煤厚分布及地质构造情况,圈出2个薄煤区域和一个高速异常区,在工作面的回采及改造中均得到了验证,为11160工作面科学回采提供了准确依据,也为不稳定煤层的探查和分析提供了一项新方法。
Xin'an coalfield is a typical coal-bed coal,whose coal seam is instability,and has brought a great deal of inconvenience,and the phenomenon of coal thinning often appear in the production process of Yunding Coal Mine Industry Co.,Ltd. With the improvement of mechanization level in coal mine,the coal seam thinner belt has more and more influence on the coal mine safety production. In order to find out the thinning range of the coal seam,multiple geophysical prospecting techniques,including pothole and trough seismic exploration technology,were used to detect and analyze the working face of Yunding Coal Mine Industry Co.,Ltd.,the distribution of coal thickness and the conditions of geological structure were obtained,the two thin coal zones and one high-speed anomaly zone were identified,which were verified in the later mining and reforming of the working face. All this has provided scientific basis for the scientific mining of 11160 working face,and also has proposed a new approach for the exploration and analysis of the unstable coal seam.
