乡镇工业在生产过程中部份会产生一些尘毒,若不采取降低尘毒浓度措施及加强个人防护,会导致生产者受到尘毒危害。为了解此类企业劳动卫生与尘毒危害情况,给治理提供参考,我们对某乡镇办的钨矿劳动操作场所粉尘浓度及接尘者矽肺患病情况进行调查,结果如下:①现场情况:该矿于1972年投产,以产钨矿为主,离县城一百多公里交通不便,冬天旱季生产和生活用水困难。掘矿人员20～80人,并逢年过节放假,农忙的早晚两造回家务农,每年仅有约三分之一或一半时间采矿,掘矿者每1～3年轮换一批。采矿设备简陋,技术落后,多为手工操作,劳动强度较大,无完善安全防尘操作规章制度,个人防护差,大多数操作者不戴口罩,无防水雨衣。对水风钻凿眼不熟练,导致凿眼进度慢,水喷激湿衣服,不懂维修湿
Township industries in the production process will produce some dust poisoning in part, if not to reduce the dust concentration measures and strengthen personal protection, will lead to the production of dust hazards. In order to understand the situation of labor hygiene and dust poisoning of such enterprises and to provide reference for governance, we conducted a survey on the dust concentration and the prevalence of silicosis in dust mines in a township-run tungsten mine. The results are as follows: ① Site situation: Ore put into operation in 1972 to produce tungsten ore-based, more than 100 kilometers away from the county traffic inconvenience, winter dry production and domestic water supply difficulties. 20 to 80 people digging, and holidays on holidays, sooner or later busy farming back home farming, only about one-third or half of each time mining, mining every 1 to 3 years a number of rotation. Poor mining equipment, backward technology, mostly manual operation, labor-intensive, no perfect security dust operating rules and regulations, poor personal protection, most operators do not wear a mask, no waterproof raincoats. Air-boring drill unskilled, resulting in chiseling slow progress, water spray wet clothes, do not know how to repair wet
