It promotes.Using water jet in coal seam pressure break after slot, control critical eigenvalue propagation direction can be played, increase pressure break range, improve
The effect of extracting result, while pressure break, the construction volume of extraction borehole, reduction coal bed gas extraction time can be reduced.
Existing underground coal mine water jet system usually goes out near connecting pipe to working face in pump discharge, water tank and water pump
Equal jet flow generating apparatus are mutually indepedent, and carry out manual adjustment face pressure in working face arrangement of valves, cannot reach more intelligent control
System, feedback to ground is only jet pressure.
Problem existing for existing underground coal mine water jet system is as follows:
1, since impact force determines high pressure water flow to the function and effect of body surface, due to being influenced by fluid behaviour, water
The impact force that the high pressure water flow generated at jet nozzle generates body surface is by factors such as spray distance, nozzle structure materials
It influences, surge is non-constant.
2, existing equipment is irremovable, is usually in the outlet port of water pump acquisition pressure as water jets impact wink
When pressure parameter be supplied to controller, farther out due to water pump distance construction place, pipeline is longer, in this way can lead to outlet pressure
And calculated value generates deviation, influences controller to the accuracy of jet vectoring.
3, since underground equipment is more, jet stream generating system pipeline is more, interferes with each other between equipment, and the height that machine generates
Decibel noise, seriously endangers the physical and mental health of people.
