四川石棉矿第一采场是一个有近三十年开采历史的老矿,过去由于没有认真贯彻貧富兼采的方针,形成下部超前,开采顺序不合理;采矿方法落后,回收率低;井下的提升、通风、排水、压风、供水、供电等系统没有形成;凿岩、放炮.运输完全靠手工劳动,工效低,产量少,不能满足国家对石棉日益增长的需要。 The first stope in Sichuan asbestos mine is an old mine with nearly 30 years of mining history. In the past, due to the failure to conscientiously implement the principle of both rich and poor, the past was formed in the lower part and the order of mining was unreasonable. The mining methods were backward and the recovery rate was low. Ascending, ventilation, drainage, air pressure, water supply, power supply and other systems did not form; rock drilling, blasting. Transport entirely by manual labor, low efficiency, less output, can not meet the country’s growing demand for asbestos.
