摘要
利用YCSZ(A)存储式随钻轨迹测量仪采集探管内部传感器磁强计和加速度计,对钻孔随钻轨迹进行分析,绘制钻孔竣工图,分析顺层抽采钻孔空白带情况,为解决回采工作面补充实施顺层钻孔区域防突措施提供可靠依据,提高顺层钻孔区域防突措施实施的有效性。
Using YCSZ （A）stored-type MWD tool to collect the internal sensor magnetometer and accelerometer,analyze the trajectory of drilling,draw the as-built drawing, analyze the blank belt of the bedding gas drainage,provide the reliable target to solve the mining face to provide the reliable target for the regional outburst prevention measures of the bedding drilling area, and improve the effectiveness of the implementation of the bedding drilling regional outburst prevention measures.
