Abstract
The invention discloses a drilling tool for an anti-blocked hole. The drilling tool is characterized in that a tee is arranged on a water supply joint of the bottom end of a drilling machine and a drill stem; the aim of the drilling tool is that when pulverized coal and gas in the hole coact to block a drilling hole and a crown drill can not continuously drill, the tee arranged on the water supply joint is operated so that high-pressure air and water are pressed to the drilling hole to discharge the pulverized coal in the hole; simultaneously, as the air pressure is increased, the gas in the hole wall can not pour out, thereby achieving the function of dredging the drilling hole and reducing the poured gas.
Description
Technical field: borehole block-resistant drilling tool belongs to the safety of coal mines field, drills when being specially adapted to the down-hole drilling plug-hole.
Background technology: by retrieval, drill under the coal mine at present, meet that the boring coal dust is many, Gas big, when the situation such as plug-hole occurring, could continue to drill after must taking to wait for gas pressure decline, invented borehole block-resistant drilling tool for addressing this problem us.
Summary of the invention: borehole block-resistant drilling tool is characterized in that at rig and drilling rod least significant end drilling rod water supply joint a threeway being installed, its objective is in the hole, coal dust, gas acting in conjunction block boring, when crown drill can't continue to drill, start the threeway of installing on the water supply joint, high pressure gas and hydraulic pressure are entered boring, and coal dust in the hole is discharged, simultaneously because the air pressure increasing, gas on the hole wall can't be gushed out, thereby plays dredging boring, reduces the effect of Gas.
Borehole block-resistant drilling tool compared with prior art has the following advantages:
1, improves the operating efficiency of boring, eliminated the shortcoming that brill, bit freezing are blocked up in boring.
2, can play the big shortcoming of gas emission in the reduction boring.
3, because with the dredging drilling action of calming the anger, so do not destroy the boring internal structure, can effectively reduce plug-hole, the generation in the hole of collapsing.
Description of drawings:
Accompanying drawing is the borehole block-resistant drilling tool schematic diagram.
1, terminal drilling rod; 2, water supply joint; 3, threeway.
The specific embodiment: now illustrate to the drawings as examples: borehole block-resistant drilling tool is characterized in that at rig and drilling rod least significant end drilling rod (1) water supply joint (2) threeway (3) being installed, its objective is in the hole, coal dust, boring is blocked in the gas acting in conjunction, when crown drill can't continue to drill, start the upper threeway (3) of installing of water supply joint (2), high pressure gas and hydraulic pressure are entered boring, and with coal dust discharge in the hole, simultaneously because the air pressure increasing, gas on the hole wall can't be gushed out, thereby play dredging boring, reduce the effect of Gas, realized borehole block-resistant drilling tool.
Claims (1)
1, borehole block-resistant drilling tool is characterized in that at rig and drilling rod least significant end drilling rod (1) water supply joint (2) threeway (3) being installed, its objective is in the hole, coal dust, gas acting in conjunction block boring, when crown drill can't continue to drill, start the upper threeway (3) of installing of water supply joint (2), high pressure gas and hydraulic pressure are entered boring, and with coal dust discharge in the hole, simultaneously because the air pressure increasing, gas on the hole wall can't be gushed out, thereby play dredging boring, reduce the effect of Gas.
