鉴于煤矿粉尘对井下安全生产和工人身体健康的危害,作者运用空气动力学和统计学原理,对矿井气象条件下的全尘和呼吸性粉尘进行了深入研究,明确了两者间的概念界限,并通过两种型号全新仪器的井下对比性监测,显微镜下逐粒分析和计算机程序处理,对双鸭山煤田具体条件下的8对生产矿井,227个采掘工作面,2166个产尘作业空间的飞扬粉尘进行数千次观测研究,从而得出了呼吸性粉尘与全尘的百分比关系,找出了呼吸性粉尘的粒径峰值;弄清了防治呼吸性粉尘的可行措施。同时还研究了国内外尘肺病防治的最新成果,根据煤、矽肺病患者死亡肺内粉尘沉积量推算出煤矿全尘、呼吸性粉尘安全卫生允许浓度标准的计算方法。
In view of coal mine dust on the safety of workers downhole and hazardous health hazards, the author of the use of aerodynamics and statistical principles of mine weather conditions of all dust and respiratory dust carried out in-depth study, a clear concept of the boundaries between the two, And through the comparison of downhole monitoring of two new types of instruments, particle-by-particle analysis under microscope and computer program processing, 8 pairs of production mines, 227 mining faces and 2166 flying dust-producing dusts After thousands of observations, the relationship between the percentage of respiratory dust and total dust was obtained, and the peak value of respiratory dust was found out. The feasible measures for prevention and treatment of respiratory dust were clarified. At the same time, the latest achievements in the prevention and treatment of pneumoconiosis at home and abroad were also studied. According to the amount of dust deposition in the lungs of coal and silicosis patients, the calculation method of allowable concentration standards for safety and sanitation of dust and respiratory dust in coal mines was calculated.
