采用崩落法开采的高硫发火矿床,在生产过程中产生高温高压有毒气体带着干粉尘喷出的事故为数不少。铜陵有色金属公司铜官山铜矿,用竖分条(分段)崩落法开采的松树山矿区,1970～1974年间曾发生10余次气喷事故;黑龙江西林铅锌矿(用深孔崩落法开采)和广西大厂矿务局铜坑锡矿(用无底柱分段崩落法开采),分别于1987年8月和7月发生了类似的事故。可见气喷事故是崩落法开采高硫发火矿床的一个较普遍的安全问题。
The use of caving mining high-sulfur pyroxene ore deposits in the production process produces high temperature and pressure toxic gases with dry dust spit out the accident a large number. The Tongsanshan copper mine of Tongling non-ferrous metal company, which was mined by vertical sub-strip (sub-section) caving method, suffered more than 10 gas-jet accidents from 1970 to 1974. The Xiling lead-zinc mine in Heilongjiang Mining) and Tongkeng Tin Mine of Guangxi Dachang Mining Bureau (exploited by non-pillar caving), similar incidents occurred in August and July 1987, respectively. It can be seen that gas-jet accident is a more common safety issue for caving mining of high-sulfur-burial deposits.
