Detailed Description
Hydraulic tunnel drilling in coal mine
1.Large drilling ability
2.high speed, simple operation
3.stable and reliable work
4.convenient mobile installation
The drilling machine is mainly used in the coal mine drilling hole, grouting fire extinguishing gas suction (row) of hole and coal seam water injection hole, outburst prevention pressure relief hole, hole and other engineering geological exploration. Suitable for rock rigidity coefficient f 10 or less of all kinds of coal seam, rock formations. Drill basic parameters can be specified in the table within the scope of the azimuth Angle and tilt Angle of drill hole.
It points column frame and mount two drill stand form, can choose according to level of the coal mine roadway and the use of different drilling. In the rig is equipped with a high pressure water generator and selects the high pressure sealing pipe for low permeability coal seam can be slotted, so as to improve the efficiency of gas drainage and shorten the extraction time. This drill adopts hydraulic drive mechanism, has great capacity of drilling, high speed, simple operation, stable and reliable work, mobile installation is convenient wait for a characteristic.
