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

Embodiment 1

[0035] Such as Figure 1-6 The blowout preventer for water exploration and discharge drilling shown includes a drill pipe 1, an ore body 2 and a borehole 3. The drill pipe 1 is plugged into the ore body 2 through the drilling rig equipment and a borehole is formed on the ore body 2. 3. The borehole 3 is located at the port on the outer wall of the ore body 2. A diversion mechanism is provided to guide and divert the water flowing out of the borehole 3. The diversion mechanism includes a fixed plate 4 with a round hole 41 in the center. The guide tube 8 on the disk 4 and in a ring structure, the guide tube 8 is hollow inside and the upper and lower ends are open, and the guide tube 8 and the circular hole 41 are concentrically arranged, and the inner diameter of the guide tube 8 is equal to the circular hole 41 diameter, and the diameters of the guide tube 8 and the round hole 41 are larger than the diameter of the borehole 3, the outer wall of the guide tube 8 is provided with...

Embodiment 2

[0038] The difference between embodiment 2 and embodiment 1 is that, as Figure 7-9As shown, the bottom of the fixed plate 4 is provided with a protective mechanism for gathering the water flow at the lower end of the circular hole 41. The protective mechanism includes a bellows 12 arranged at the bottom of the fixed plate 4 and having a diameter greater than the diameter of the circular hole 41. The adjustment mechanism on the flow tube 8 and the telescopic control of the bellows 12, the upper port of the bellows 12 is fixedly connected with the bottom end of the fixed plate 4 through the upper connecting ring 13, and the lower port of the bellows 12 is fixedly connected with the drill hole 3 The lower connecting ring 16 with the port covered can cover the area between the port of the borehole 3 and the fixed plate 4 through the bellows 12, so that more water flowing from the borehole 3 can flow into the guide tube 8, to reduce the outflow of water flow from the lower port of...

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...
