【摘要】：煤矿工人是我国尘肺病的高发人群。随着矿井采掘机械化水平提高,开采深度加大,煤矿井下采掘工作面粉尘危害程度也越来越大。由于采掘工作面装备不同、防尘设施不同,工种不同,工人的接尘水平差别较大,对人体造成的危害程度也不同。为了客观评价我国煤矿采掘工作面粉尘危害,以桑树坪煤矿新建矿井为对象,在生产设备运转,防尘技术措施运行情况下,对综采工作面、综掘工作面、炮掘工作面各岗位工种作业地点呼吸性粉尘进行了个体采样,实验室测定了各工作场所的粉尘游离SiO_2含量、分散度和呼吸性粉尘浓度。结合检测数据和防尘、降尘设施实际情况,分析了超标原因,明确防尘重点岗位,提出了粉尘危害防治措施。
[Abstract]:Coal miners are a high incidence of pneumoconiosis in China. With the improvement of mining mechanization level and mining depth, dust hazard in underground mining face is becoming more and more serious. Because of different equipment, different dust prevention facilities and different types of work, the level of dust exposure of workers is quite different, and the degree of harm to human body is also different. In order to evaluate objectively the dust hazard in the coal mining face of our country, taking the new coal mine of Sangshuping coal mine as the object, under the condition of the operation of the production equipment and the technical measures of preventing dust, the fully mechanized mining face and the fully mechanized excavating face are studied. Individual samples of respirable dust were collected from various job sites in the working face. The content of free Sio _ 2, dispersion and respiratory dust concentration in each workplace were measured in laboratory. Combined with test data and actual situation of dustproof and dedusting facilities, this paper analyzes the reasons for exceeding the standard, defines the key post of dustproof, and puts forward the prevention and control measures of dust hazard.
