开拓巷道是煤矿基本建设主要工程,服务年限长,技术要求严。由于它的重要性,煤炭部规定的生产矿井八项经济指标中,把开拓进尺作为一项重要的考核指标,1985年至1990年煤炭部对统配煤矿实行经济总承包,也把开拓进尺作为一项重要的承包内容。为了客观地反映矿井开拓状况,煤矿测量人员对开拓进尺的正确丈量统计是十分重要的,而准确地划分开拓巷道的范围,又是正确统计的基础。不过现有关于开拓巷道的划分规定尚有某些不一致的地方,急待统一。关于开拓巷道划分部颁有三个文件:
Open roadway is a major project of coal mine infrastructure, long service life, strict technical requirements. Because of its importance, the Ministry of Coal provides eight major economic indicators of production mines, to develop the footage as an important assessment indicators, from 1985 to 1990, the Ministry of Coal economy of the coal mines to implement economic general contracting, but also to open up the footage as a An important contracting content. In order to objectively reflect the status of mine development, coal mine surveyors to measure the accuracy of the development of footage is very important, and accurately divided the scope of the development of roadway, but also the basis for correct statistics. However, there are still some inconsistencies in the existing provisions concerning the division of roadways in development and the urgent need for reunification. On the development of roadway division awarded three documents:
