煤矿立井井筒工程虽仅占矿井井巷工程量的3～5％,而工期往往要占建井总工期的40～50％,并且目前煤矿在建矿井很多仍是处于凿井阶段的,故加快立井工程速度对加快煤矿建设、尽快发挥投资效益是极为重要的关键。煤炭部基建司组织召开这次立井技术座谈会,邀集了若干我国煤矿立井建设工程的技术骨干,进行了全面的技术座谈。刘辉副部长(下转第64页)
Mine shaft mine shaft project accounts for only 3 ~ 5% of mine shaft and tunnel engineering, but the construction period often accounts for 40 ~ 50% of the total construction period, and the coal mines in the construction of a lot still in the sinking stage, it is accelerating The speed of shaft engineering is crucial to accelerate the construction of coal mines and to bring the investment returns as soon as possible. The Infrastructure Department of the Ministry of Coal Mine organized and held this symposium on shaft technology, invited a number of technical backbone of China’s coal mine shaft construction project and conducted a comprehensive technical discussion.
