冷水江煤矿塘冲矿井的地质采勘对比分析

MINING-PROSPECTING COMPARATIVE ANALYSIS OF TANGCHONG MINING SHAFT OF LENGSHUIjIANG COAL MINE

塘冲矿井的大量井巷地质资料与原勘探精查报告对比分析表明,原精查报告内容与实际情况有较大出入,特别是控煤褶皱、断裂,煤层厚度与储量等方面,都存在较大差异,对矿山采矿影响颇大。究其原因,可能是勘查阶段受规范和技术手段等的限制,使原报告精度不够。因此,本文提出改进勘探方法,完善规范,提高勘查精度和加强煤矿生产补充勘探,都显得十分重要。

Comparative analysis between mining geological data and the former geologio prospecting report in Tangchong mining shaft indicates that the content of the prospecting report is largrly divergent from practice, especially in the aspects such as coal-controlling foldings and faults, coal seam thickness and coal reserve, which greatly affected the mining in the mine. The reason may lie in the deficient prospectng precision arisen from the restriction of the standard and technical means during the prospecting stage. Therefore, it is suggested in the paper that improving the prospecting means, consummating the standard, raising the prospecting precision and enhancing the supplemenary productive prospecting of coal mines appear to be very important.
