非瓦斯矿凿岩、出矿时连续排放的有害物质主要是矿尘。如果在图1支管上安设一个除尘器(图1B),则污风被净化为新风。此时只要根据产尘强度调节循环风量,就可使工作面粉尘浓度达到规定标准。因而,这种带除尘器的半循环通风就可能解决独头掘进时的排尘、排烟问题。 (一)独头巷道半循环通风过程分析如图1B所示,设产尘强度为F(毫克/秒)、
Non-gas mine rock, mine discharge continuously harmful substances are mainly mine dust. If a dust collector is installed on the branch pipe of Figure 1 (Figure 1B), the dirty air is purified to fresh air. At this time, as long as the circulating air volume adjustment according to the intensity of dust, you can make the face dust concentration to meet the required standards. Therefore, the semi-circulation ventilation with this dust collector can solve the problems of exhaust dust and smoke exhaust during the digging operation. (A) semi-circular roadway ventilation process analysis shown in Figure 1B, set the dust intensity of F (mg / s)
