锦西市位于辽宁西部,是个多山地区,自然资源非常丰富,随着乡镇企业的发展,采矿业已占乡镇企业的17%,主要开采金矿、钼矿、铜及铅锌矿等。随着生产规模的不断扩大,产品种类内不断增加,矿山的污染问题也日趋严重。在未治理前,多数矿都为干凿岩,井下粉尘浓度远远超过国家允许的标准。针对乡办企业工艺落后,设备简陋,工人多数来自于农村,一旦得了矽肺生活无保障的特点,我们在乡办矿山推广了湿式凿岩法,使井下作业环境的粉尘浓度达到或接近国家允许浓度,基本上解决了粉尘的污染问题。我们的具体作法是: Located in the western part of Liaoning Province, Jinxi City is a mountainous area with abundant natural resources. With the development of township and village enterprises, the mining industry accounts for 17% of the township enterprises and mainly produces gold, molybdenum, copper and lead-zinc deposits. With the continuous expansion of production scale, product categories continue to increase, the problem of pollution in mining is also increasingly serious. Before being governed, most of the mines are dry rock drills, and the downhole dust concentration far exceeds the national standard. For the township enterprises behind the technology, simple equipment, the majority of workers from rural areas, once got the silicate-free life-saving features, we promote the village office mining wet rock drilling method, so that dust concentration downhole operating environment at or near the national allowable concentration , Basically solved the problem of dust pollution. Our concrete approach is:
