摘要
煤矿井下巷道断面尺寸的大小会影响测量误差,大断面巷道测量存在环境复杂、对中困难、破碎测量点难保全等问题。针对坡底煤业大断面巷道的实况,设计了大断面巷道一次成巷贯通测量方案,结果实现施工高精度贯通,贯通后巷道中线和腰线的偏差符合要求,贯通测量方案合理。
The section size of underground roadway in coal mine will affect the measurement error.There are some problems in the measurement of large section roadway,such as complex environment,difficult alignment,difficult to ensure the integrity of broken measurement points and so on.According to the actual situation of large cross-section roadway in slope bottom coal industry,the one-time roadway penetration measurement scheme of large cross-section roadway is designed.The results show that high-precision penetration is realized,the deviation of roadway center line and waist line after penetration meets the requirements,and the penetration measurement scheme is reasonable.
