摘要
为了保证诚南煤业15102回采工作面的安全开采,采用无线电波和瞬变电磁法对回采工作面可能存在的构造和煤层变薄区及含水区进行探测,并采用钻探法进行验证。综合分析认为:工作面回采至50~100 m、200 m左右、350~400 m及550~650 m时可能存在构造和煤层变薄的情况;回采至60~160 m、200~240 m、280~460 m、520~680 m范围内可能存在顶板裂隙水。
To ensure the safe mining of 15102 working face in Chengnan Coal Industry,the possible structure,coal seam thinning area and water bearing area in the working face are detected by radio wave and transient electromagnetic method,and verified by drilling method.According to the comprehensive analysis,when the working face reaches 50m to 100m,200m,350m to 400m and 550m to 650m,there may be thinning of structure and coal seam;when it is mined to 60m to 160m,200m to 240m,280m to 460m and 520m to 680m,there may be roof fissure water.
