Abstract
A pump collects waste fluid and debris from the drilling of a borehole in a mine and for disposing of the waste fluid in a controlled manner. The pump collects the waste fluid into the pump housing through a grate. The pump also includes a centrally located hole which allows a drilling shaft to pass through the body of the pump. The pump further includes a funnel-shaped collar for collecting waste fluid that is dispersed from the mine borehole. A drill head may be attached to the pump for powering the drilling shaft, and for powering an impeller within the pump.
Claims16
An apparatus for use in wet drilling a face of a mine passage with a fluid, said apparatus comprising:
- a drill head for drilling the face using the fluid;
- and
- a centrifugal pump associated with the drill head for receiving used fluid and for directing used fluid away from the drill head;
- wherein the drill head and the centrifugal pump each include an opening for receiving a drilling member for drilling the face of the mine passage.
An apparatus for use with a drilling shaft in wet-drilling a face of a mine passage with a liquid, said apparatus comprising:
- a drill head for powering the drilling shaft for drilling the face in connection with the liquid;
- and
- a centrifugal pump adapted for receiving used liquid and for directing said liquid away from the drill head;
- wherein the drill head is associated with a first motor for driving the drilling shaft and the centrifugal pump.
An apparatus for use in wet drilling a face of a mine passage with a fluid, said apparatus comprising:
- a drill head for drilling the face using the fluid;
- and
- a centrifugal pump associated with the drill head for receiving used fluid and for directing used fluid away from the drill head,
- wherein the pump includes a housing forming a chamber surrounding an impeller;
- wherein the housing further includes an inlet and an outlet;
- wherein the inlet includes a frustoconical collar for directing fluid into the pump.
An apparatus for use with a drilling shaft in wet-drilling a face of a mine passage with a liquid, said apparatus comprising:
- a drill head for powering the drilling shaft for drilling the face in connection with the liquid;
- a centrifugal pump adapted for receiving used liquid and for directing said liquid away from the drill head;
- and
- a pump housing, said pump housing comprising an inlet concentric with the drilling shaft and an outlet.
An apparatus for use with a drilling shaft in wet-drilling a face of a mine passage with a liquid, said apparatus comprising:
- a drill head for powering the drilling shaft for drilling the face in connection with the liquid;
- and
- a centrifugal pump adapted for receiving used liquid and for directing said liquid away from the drill head;
- wherein the drill head and centrifugal pump each include an aperture for receiving the drilling shaft, and wherein the apertures are concentrically aligned.
