【摘要】 随着掘进工作面生产现场综合机械化程度的不断提高,煤矿半煤岩巷道掘进方式逐渐由放炮掘进改为综掘,显著地提高了掘进效率,保障了施工安全,降低了职工的劳动强度,但是也带来了新的问题:半煤岩巷道机掘过程中,产尘量增大。为了解决此问题,文章分别针对半煤岩机掘巷道迎头、转载点以及回风巷道3个位置进行治理,形成了半煤岩巷道机掘工作面迎头以除尘为主、转载点以控尘为主、回风巷道以捕尘为主的综合防尘体系,有效地降低了半煤岩机掘巷道的粉尘浓度。更多还原

【Abstract】 With the increasing of integrated mechanization of tunneling working face,the way of tunnelling working method semi-coal seam used to be the explosion tunneling,which has been replaced by the way of integrated tunneling.This method increases the efficiency of tunneling,ensures the construction safety and reduces workers’ working intension.However new problem has brought up,it is the accretion of dust.This essay has discussed the renovation method on the semi-coal seam mechanization tunneling laneway,reshipment place and airiness lane way.更多还原
