鹤壁煤电公司九矿位于鹤壁煤田北部,面积6.2km~2。1960年简易投产,设计生产能力30万t/a。2004年矿井进行改扩建,风量由原来的4000m~3/min,增大到5300m~3/min,+15水平运输大巷风速处于临界状态。+15大巷是该矿主要运输大巷,采用ZK7-6/250型电机车牵引MG-3型矿车逆风运输原煤。由于该巷风速较大,巷壁、管路和电缆粉尘堆积严重,除尘周期由原来的每月一次逐步改为每天一次,在防尘方面投入了大量的人力物力,但收效甚微。为彻底改变这种状况,该矿研制了机械防尘专用车和机械专用刷白车,达到了预期防尘效果。
Jiu Mine Hebi Coal and Electricity Company is located in northern Hebi Coalfield, an area of 6.2km ~ 2. 1960 put into operation briefly, the design production capacity of 300,000 t / a. Reconstruction and expansion of the mine in 2004, the air volume from the original 4000m ~ 3 / min, increased to 5300m ~ 3 / min, + 15 horizontal transport lane wind speed at a critical state. +15 lane is the main transport lane of the mine, the use of ZK7-6 / 250 electric locomotive traction MG-3 type of mine car against the wind transport. Due to the high wind speed in the lane, serious accumulation of dust in laneways, pipelines and cables led to a gradual change of dusting cycle from once a month to once a month. As a result, a large amount of manpower and resources have been invested in dust prevention but with little success. In order to completely change this situation, the mine developed a dust-free special vehicles and machinery dedicated white car, to achieve the expected dust effect.
