三山岛金矿溜矿系统防尘措施探讨

Investigation on Dust Prevention Measures for Sliding System at the Sanshandao Gold Mine

溜矿系统作为矿山生产工程中的关键环节,随着采矿机械化水平和矿山开采量的不断提高,各种形式的矿石溜井应用也越来越广泛。但在溜井放矿过程中,由于矿石相互碰撞破碎会产生大量粉尘,这些粉尘通过溜井与各分段巷连接处汇聚扩散,最后吹勘至整个通风系统中,严重污染了工作区域环境并直接危害工人生命安全,给生产作业带来严重安全隐患。因此,为采取有效防尘措施减少溜矿过程中粉尘逸出量,主要针对三山岛金矿溜矿系统现状,结合-600 m中段进风井石门巷溜矿系统设计,在参考国内外粉尘治理措施的基础上,对矿山溜矿系统防尘措施进行了探讨,通过采取具体措施,溜矿作业现场环境得到了较大改善,实现了预期的效果。

It is known that the sliding system is considered as the key links of mine production projects,now with the rapid improvement of mining mechanization level as well as the mining production,various forms of ore chute is becoming more and more extensively applied.However,in the chute drawing process,due to collision between ore crushing could produce a large amount of the dust,and the dust blowed to the ventilation system then diffused mainly by chute and the piecewise lane junction.Therefore,the dust around the working areas seriously polluted the environment and directly can harm the workers lives,and bring serious security hidden danger to production. Thus, in order to take effective measures for dust control to reduce slip ore dust during the process of escape,according to the present condition of Sanshandao gold mine combined with sliding system design of middle -600 m at entering wind shaft,and on the basis of reference of the dust control measures home and abroad,we discussed the mining system for the mine dust prevention measures,field environment has been improved after taking specific measures, also the desired results were achieved.
