右江矿务局新州四号井,针对软岩巷道支护质量问题,狠抓管理工作,使巷道由过去当月成巷平均45％的破坏率,做到当月基本无破坏,质量大大提高,当时每月约可节约7万元。 一、矿井及地质概况 右江矿务局新州四号井位于广西百色地区田东县境内,井田面积约12平方公里,开采深度260米左右。可采煤三层,工业储量1795万吨,可采储量1225万吨。井巷设计工程量9800米,预计1987年建成。
Youjiang Mining Bureau State No. 4 wells, soft rock roadway support for quality problems, pay close attention to management, so that the roadway into the lane from the past month the average destruction rate of 45%, so basically the same month without destruction, the quality greatly improved, At that time, about 70,000 yuan could be saved each month. I. Overview of Mines and Geology The No.4 Well of New Youzhou Mining Bureau is located in Tiandong County, Baise, Guangxi. The area of the mine covers an area of about 12 square kilometers and the mining depth is about 260 meters. Can be three layers of coal, industrial reserves of 17.95 million tons, recoverable reserves of 12.25 million tons. Well engineering design engineering volume 9800 meters, is expected to be completed in 1987.
