龙烟矿山公司是一个具有七十多年开采历史的老矿。由于地质条件复杂,开采进入深部井下巷道支护已成为一个相当突出的问题。近年来,在不良岩层巷道中,支护型式基本上延用五十年代木支架的老技术。这样的支护形式,坑木消耗多,掘进开凿量大,成巷速度慢,生产费用高。远远适应不了矿山发展的需要。去年年初,这个矿为了加速矿山生产的发展,决定将老矿的挖潜、革新、改造放到首要位置来抓,并把解决井下巷道支
Longyan Mining Company is an old mine with more than seventy years of mining history. Due to the complex geological conditions, mining into deep downhole roadway support has become a rather prominent issue. In recent years, in the poor rock roadway, the support type basically uses the old technology of the 50’s wood bracket. This form of support, pit consumption, driving a large amount of digging into the lane slow, high production costs. Far can not meet the needs of the development of mines. Early last year, this mine in order to accelerate the development of mine production, decided to tap the potential of old mines, innovation and transformation to the top position to grasp, and to solve the underground roadway branch
