江西省下陇钨矿在矿山生产中,始终坚持“安全第一、防尘至上”的方针,实行“减、降、排、护”的科学管理办法,使防尘工作取得了明显效果。该矿粉尘浓度降到2毫克以下。29年来没有发现一例矽肺病患者,受到省和中央有关部门的赞扬。他们的做法是: 一是减尘该矿矿岩含矽量高达70％以上,矽尘危害比较严重。为改变这种状况,他们在矿岩中游离二氧化矽含量越高,空气中的粉尘浓度越高,
In the mine production, the Xialong tungsten mine in Jiangxi Province always adheres to the principle of “safety first and dust prevention first” and implements scientific management measures of “reduction, reduction, emission and protection” so as to make the dust prevention work have achieved remarkable results. The mine dust concentration dropped to 2 mg or less. No case of silicosis was found in 29 years and was praised by the provincial and central authorities. Their approach is: First, the mine dust reduction in the ore containing silicon content as high as 70%, more serious damage to the silica dust. To change this situation, the higher the content of free silica in the ore rock, the higher the concentration of dust in the air,
