摘要
为了对金刚煤矿采煤工作面可能出现的各种地质异常情况进行预报、定位和分析研究,运用矿井坑道透视技术,对3116、3118、31110采煤工作面进行了探测实验与分析。实验结果表明,采用0.5 MHz频率的坑道透视技术,能够较为准确地预报出金刚煤矿采煤工作面内煤层破碎带、陷落柱,为金刚煤矿采煤工作减少了钻探费用,并提供了物探技术支持。
In order to forecast,locate and analyze various geological anomalies that may occur in coal mining face of Jingang Coal Mine, using mine tunnel perspective technology,the detection experiments and analysis of3116,3118 and31110 coal mining faces were carried out.The experimental results showed that the tunnel perspective technology with 0.5 MHz frequency can accurately predict the coal seam breakage zone and collapse pillar in the mining face of Jingang Coal Mine.It reduced drilling cost and provided geophysical support for coal mining in Jingang Coal Mine.
