摘要
为了保证煤矿井下长距离工作面准确贯通,必须制定合理的贯通测量方案,采用有效的测量方法。以黄陵二号煤矿205工作面为背景,对长距离工作面巷道贯通进行了测量设计,通过对井下导线测量与高程测量进行分析,提出了提高测量精度的可行性方法。通过对贯通测量的误差进行计算分析,检验了贯通测量方案和方法的合理性。
In order to ensure the accurate holing-through of long-distance working faces in coal mines,the reasonable holingthrough survey plan must be established and effective measurement methods should be adopted. Taking No. 205 working face in Huangling No. 2 mine as an example,the measurement design of roadway holing-through in long-distance working face was carried out. Through the analysis of underground traverse survey and elevation measurement,a feasible method to improve the measurement accuracy was proposed. By the calculation and analysis of the error of the holing-through survey,the rationality of holing-through survey plan and method was tested.
