摘要
1402工作面多断层发育,地质条件复杂,沿煤层顶板掘进巷道在长距离贯通时可能因断层影响而造成贯通误差大。针对此问题,结合相关地质资料,制定专项贯通测量方案,经2次独立贯通测量数据分析及贯通误差预计估算,贯通精度可靠。
Due to the development of multiple faults in the 1402 working face and complex geological conditions,the driving roadway along the roof of the coal seam may cause large penetration errors due to the influence of faults.In view of this problem,Xintian Coal Mine has developed a special through survey plan combined with relevant geological data.Through two independent through survey data analyses and through error estimation,the accuracy is reliable.
