在大规模经济建设的今日,采掘地下各种宝藏作为各种工业中的原料或燃料,是社会主义建设中的基本事业。在采掘地下宝藏的各种生产过程中,有很多特殊的生产性卫生问题,其中之一便是放炮後爆炸烟气的危害问题。这个问题同时也还存在於筑路的挖掘隧道等等工程中。放炮的生产过程是先用风钻、电钻或鹤嘴锹在矿石上打一个或几个孔,再放入炸药,接上电线。用泥封好,然後将电源接合。炸药爆炸时,大块的矿石就崩裂开来,这时就发生大量的灰尘与烟气。
In today’s large-scale economic construction, mining all kinds of underground treasures as raw materials or fuel in various industries is a basic undertaking in socialist construction. In the various processes of mining underground treasures, there are many special hygiene problems of production. One of them is the problem of the harm of explosion smoke after blasting. This problem also exists in excavation tunnels and other projects. Blasting the production process is to use a pneumatic drill, electric drill or pick spade in the ore hit one or several holes, and then add explosives, connected to wire. Seal with mud, then power on. When the explosives exploded, large pieces of ore burst apart, and a great deal of dust and fumes took place.
