Steeply inclined coal seam high-pressure water drilling mining device

Abstract

The invention discloses a steeply inclined coal seam high-pressure water drilling mining device. The device comprises a water drilling machine, a crusher, a spiral conveyor, a coal slime pump and coalslime dehydration equipment, the crusher is installed in an inner groove of an underground roadway, a hopper of the crusher is lower than the bottom plane of the underground roadway, and the water drilling machine is installed on a moving trolley. A discharging port of the crusher is connected to a feeding port of the spiral conveyor in a sealed manner, the spiral conveyor is installed in the underground roadway, a discharging port of the spiral conveyor is connected to a feeding port of the coal slime pump in a sealed manner, a discharging port of the coal slime pump is connected to the coalslime dehydration equipment, and the coal slime pump is installed outside the underground roadway. Rapid water mining of an inclined coal seam is achieved, sparks caused by drilling in the mining process are avoided, mining is safer, the inclined coal seam is broken into a coal slime shape, conveying of the spiral conveyor is better facilitated, under the action of negative pressure generated bythe coal slime pump, rapid discharging is facilitated, discharging is thorough, spiral conveying is achieved, the maintenance probability of the device is reduced, and the conveying efficiency is improved.

Description

Technical field[0001]The invention belongs to the technical field of coal mining devices, and relates to a high-pressure water drill mining device for steeply inclined coal seams.Background technique[0002]Existing mining methods usually use roadheaders for mining. After mining, belt conveyors are used for coal material transportation. In high gas coal seams, unstable coal seams, steeply inclined coal seams, corner coals and coal seams with small irregular reserves, it is not conducive to The normal way of mining affects its safety and mining efficiency and is suitable for hydraulic mining. Disadvantages of belt transportation: belt conveyors have the advantages of long transportation distance, large transportation capacity, low working resistance, easy installation, low power consumption, and less wear; but the disadvantage is that the inclined roadway is required to be transported upwards. The inclination angle is not greater than 18°. At 18°, the goods will slide down, and the goo...

Problems solved by technology

[0002] Existing mining methods usually use roadheaders for mining, and belt conveyors are used to transport coal materials after mining, which is not conducive to high-gas coal seams, unstable coal seams, steeply inclined coal seams, edge coal, and coal seams with small irregular reserves. The normal way of mining affects its safety and mining efficiency, and is suitable for hydraulic mining

Disadvantages of belt transportation: belt conveyor has the advantages of long transportation distance, large transportation capacity, small working resistance, easy installation, low power consumption, and small wear; but the disadvantage is that the inclined roadway requires an inclination angle of no more than 18° when transporting upwards, greater than When it is 18°, the goods will slide down, and the goods cannot be pulled up. When transporting inclined downhill, the inclination angle should not be greater than 15°. , the belt will run forward with the coal unloading drum, so that the goods on the belt will be piled up on the driving drum; the other is that although the belt stops, due to the large slope and small resistance, the goods will slide down by themselves, and the goods cannot be controlled, and a Stacking phenomenon
