水力运输的任务即是将采落的煤经过井下巷道输送到井筒,远至地面的选煤厂或者直接运给用户.在水力采煤矿井中广泛应用了溜槽自流水力运输.采用此法,巷道的坡度不得小于0.05,有时巷道可沿煤层的倾向或者按一定的“倾角”掘进.煤浆由工作面自行流入水力提升室中的煤浆贮槽里.大块煤进入煤水泵前,经破碎机破碎成与煤水泵工作输出口尺度相应的块度—60—70毫米.现在水力采煤矿井采用的Д-2型和ДМⅢ-1型锤式破碎机,是连续式操作,但具有破煤过碎的缺点.
The task of hydraulic transportation is to transport the coal collected through underground tunnels to the wellbore as far as the coal preparation plant on the ground or directly to the users.With the adoption of this method, The slope of the roadway shall not be less than 0.05, and sometimes the roadway may be driven along the tendency of the coal seam or according to a certain “dip angle.” Coal slurry flows into the coal slurry storage tank in the hydraulic lifting chamber by itself, Broken crusher broken into coal-water pump output port size corresponding to the degree of -60-70 mm. Now hydraulic coal mining used Д-2 type and ДМ type III-1 hammer crusher, is a continuous operation, but with broken Disadvantages of coal crushing.
