Water exploration and drainage borehole blowout prevention water segregator and working method

Abstract

The invention discloses a water exploration and drainage borehole blowout prevention water segregator and a working method, and belongs to the technical field of coal mine safety production. The waterexploration and drainage borehole blowout prevention water segregator comprises a drill rod, an ore body and drill holes, wherein the drill rod is inserted in the ore body through drilling machine equipment and forms the drill holes in the ore body, a diversion mechanism for guiding and diverting water flow gushing out of the drill holes is arranged at the end opening, located on the outer wall of the ore body, of the drill holes and comprises a fixed disc with a round hole formed in the center and a flow guide cylinder fixedly arranged on the fixed disc and of an annular structure. Accordingto the water exploration and drainage borehole blowout prevention water segregator and the working method, when a large amount of water flows out of the drill holes, most of the gushing water flow can be guided through the flow guide cylinder and finally discharged from a water outlet pipe at a water outlet in the flow guide cylinder, so that the gushing water flow are prevented from directly rushing to the drilling machine equipment, and the drilling machine equipment is protected; meanwhile, the possibility that the gushing water flow impacts people around the drilling machine equipment canbe reduced, so that people are protected.

Description

technical field [0001] The invention relates to the technical field of coal mine safety production, in particular to a blowout-proof water separator for a water exploration and discharge drilling hole. Background technique [0002] At present, in the mining industry, geophysical prospecting cannot accurately describe the water-bearing state in the formation, and can only roughly delineate the water-bearing area. The work of exploring and releasing water is still one of the main means to prevent, control and rectify water damage and ensure safe production in mines; [0003] According to the requirements of the regulations, during the construction process of water exploration and drainage, it is necessary to accurately grasp the water outlet conditions of the water exploration and drainage holes and the water inflow from the boreholes, so as to provide basic information for the water exploration and drainage work. In the past construction process, during the drilling construct...

AI Technical Summary

Problems solved by technology

In the past construction process, during the drilling construction process, when the water came out of the hole, if it was too late to pull out the drill hole, the only option was to put the drill pipe into the hole, and then close the valve to stop the water. If the drill pipe was pulled out, the hole would be There will be water gushing out. When the water gushing out of the borehole is large and the pressure is high, the gushing water will rush directly to the drilling rig equipment, which will cause damage to the drilling rig equipment. At the same time, the gushing water will also affect the The impact of the crowd around the drilling equipment will affect the safety of people
