随着采掘机械化水平和产量的提高,矿井大气含尘量增加。这就要求在高尘煤层(产生煤尘比大于400克/吨)防尘措施的综合效果不低于99％。 为此,在煤矿进行了一系列全新方案的研究。这些方案主要有:研究煤尘粒子不同变态阶段除尘溶液作用的理论机理;研究煤尘的电物理和物理化学性质,在此基础上应用水无火花再充电方法的科学特点,安装保极体喷雾器;确定煤体产生煤尘量和规定在康拜因掘进巷道的情况下,应用各种防尘方法的范围;根据煤尘性质和当代与未来的抑尘手段的可能性,制定并选择采煤和掘进巷道时水力除尘方式和参数的方法。
With the increase of mining mechanization level and output, the amount of dust in mines increases. This requires that the combined effect of dust control measures in high-dust coal seams (with a dust-to-dust ratio greater than 400 g / t) is not less than 99%. To this end, conducted a series of new programs in the coal mine research. These programs mainly include: study the theoretical mechanism of dust removal solution in different metamorphosis stages of coal dust particles; study the electrical and physical and chemical properties of coal dust, based on the scientific characteristics of water non-spark recharging method, ; Determining the amount of coal dust generated by the coal and specifying the range of dust protection methods to be applied in the context of the tunneling of the Kang Baines; and formulating and selecting the coal mining based on the nature of the coal dust and the possibility of dust suppression, both contemporary and future And roadway excavation method of hydraulic dust and parameters.
