三元中能煤业2306工作面巷道贯通测量分析研究

Analysis and Research on Roadway Holing Through Survey in 2306 Working Face of Sanyuan Zhongneng Coal Industry Co., Ltd.

分析了三元中能煤业2306工作面顶底板岩性,制定了2306工作面运巷切眼、回风巷贯通方案,进行了误差预计,通过现场实测确定了水平误差、垂直误差、角度闭合差和导线闭合差,并与预计误差进行了对比分析,提出了建立地面控制网且加测陀螺定向边来提高测量精度,确保巷道准确贯通。

This paper analyzed the lithology of roof and floor of 2306 working face in Sanyuan Zhongneng Coal Industry Co.,Ltd.,and formulated the cut-through plan of cutting hole of haulage roadway and air return roadway in 2306 working face,predicted the error,determined the horizontal error and vertical error,angle closure error and wire closure error by field measurement,compared with the predicted error,and put forward the establishment of the ground control network and the addition of gyroscopic orientation side to improve the measurement accuracy,so as to ensure the accurate penetration of the roadway.
