一、概况全岩掘进机在施工过程中,由于破岩、卸料、运输、转载以及支护钻孔,使岩尘飞扬,巷道的粉尘从每立方米空气中几十毫克、几百毫克乃至几千毫克,成了矿井灾害主要害源之一。根据国内资料统计,煤矿尘肺的结核发病率约在10～30％,严重的粉尘超限量还可能导致其它公害与不测事故的发生。针对产尘的因素和尘源状况,过去主要采用以下一些防治措施: (1).选择合理的刀具参数; (2).采用喷雾洒水; (3) 选用高效的除尘装置; (4).刀盘后增设夹层档板; (5).组织巷道气流。通过以上措施,虽然粉尘有所下降,但剩余的粉尘浓度很难达到《工业企业安全和卫生规范》的要求,经实测粉尘的峰值依旧超过允许浓度的几倍或几十倍。因此,加速研制一种高效除尘装置及方法,使巷道空气中的含尘浓度接近或达到 First, the overview Whole rock bolting machine in the construction process, due to rock breaking, unloading, transportation, reprinting and support drilling, so that rock dust flying, roadway dust from the air per cubic millimeter, tens of milligrams and even hundreds of milligrams Thousands of milligrams, has become one of the major sources of mine disasters. According to statistics from domestic sources, the incidence of pneumoconiosis in coal mines is about 10% to 30%. Severe dust excess can also lead to other public hazards and unexpected accidents. In view of the dust producing factors and dust source conditions, some of the following prevention and control measures were mainly adopted in the past: (1) to choose a reasonable tool parameters; (2) to use spray sprinkler; (3) to choose an efficient dust removing device; (4) After the sandwich plate additional; (5). Organization of roadway airflow. Through the above measures, although the dust has declined, the remaining dust concentration is difficult to meet the requirements of “Safety and Health in Industrial Enterprises”. The measured dust peak is still several times or more than the allowable concentration. Therefore, to speed up the development of an efficient dust removal device and method, so that the dust concentration in the air near or into the roadway
