摘要
以演马庄矿27131下段工作面实际地质情况为背景,采用无线电波透视技术探测采煤工作面中的隐伏瓦斯地质异常区域,对整个工作面的瓦斯地质异常做整体分析评价。通过采用定点扫描法3种频率对工作面进行探测,圈定3处较为集中的异常区,并分析推断引起物探异常区的原因,在27131下段工作面回采过程中都得到了进一步的验证,与采前的分析结论基本一致。
Taking practical geological conditions of 27131 lower working face in Yanmazhuang Mine as background,radio waves perspective technology was adopted to detect blind gas geological abnormal zone in coal face,the gas geological abnormal of whole working face was analyzed and evaluated overall.Through detecting the working face with three detecting frequency of fixed point scanning method,three concentrated abnormal zones were determined,and the geophysical abnormal reason was analyzed and concluded,and the results were further verified during the mining process of 27131 lower working face and were consistent with the analysis of conclusion before coal face mining.
