More Information
Summary:Novel measurement of water conservancy reaming volume of expanding coal device, the device including the mine car of laying track in the tunnel, advance along the track, establish rig and high -pressure pump system, the precipitation bucket in the tunnel and establish in precipitation bucket and upwards stretch out precipitation bucket's cartridge filter, rig and the transmission of high -pressure pump system are connected with reaming drilling rod and drill bit. The utility model discloses can ensure the underreamed effect of water conservancy to a certain extent to and then guarantee layer drilling gas drainage effect, and be favorable to help to promote mine gas improvement level, ensure coal mine safe production, and do benefit to the popularization and application of water conservancy reaming new technology.
