矿井巷道贯通测量及其精度控制技术研究

Study on Through Measurement and Precision Control Technology of Mine Roadway

巷道贯通工程效率、质量等直接影响后续生产,高精度贯通测量是确保巷道高效掘进基础。以北翼进风斜井距离贯通测量为工程背景,提出采用TC402全站仪进行贯通测量,并依据现场实际情况提出针对性的贯通精度控制措施。现场应用后,巷道贯通点位置测量误差均在允许范围内,现场取得较好应用成果。

The efficiency and quality of roadway penetration engineering directly affect the subsequent production. High precision penetration measurement is the basis to ensure efficient roadway excavation. Based on the engineering background of the penetration measurement of the distance of the north air inlet inclined shaft, it is proposed to use TC402 total station for penetration measurement, and put forward targeted penetration accuracy control measures according to the actual situation of the site. After field application, the measurement errors of roadway penetration points are within the allowable range, and good application results are obtained on site.
