Description

A kind of descending boring drainage arrangement
Technical field
This utility model relates to a kind of descending boring drainage arrangement, especially with the descending boring drainage arrangement of negative pressure extraction.
Background technology
In process of coal mining, arranging that boring carries out gas pumping for projecting coal bed needs, due to the complexity of coal mining geology, part boring adopts lower line mode to carry out gas pumping. Owing to process of drilling adopts wet type drill and there is part crevice water in coal seam, cause and in boring, there is hydrops, negative pressure extraction system cannot by boring internal water accumulation discharge, boring internal water accumulation can cause gas cannot normally extraction, seriously reduce the gas pumping efficiency of mine.
Summary of the invention
The technical problems to be solved in the utility model: provide a kind of descending boring drainage arrangement, cannot get rid of solving existing descending mash gas pumping drilling hydrops, affect the problems such as gas pumping.
The technical solution of the utility model is: a kind of descending boring drainage arrangement, including the drainage tube being placed in boring and air supply pipe, drainage tube is connected with extraction system and drainage system, and air supply pipe is connected with air supply system.
Drainage tube extends to foot of hole.
Described drainage system includes the pump drainage ball being trumpet-shaped pump drainage storehouse and being placed in one.
Side, pump drainage storehouse is connected with wire netting.
Pump drainage storehouse and drainage tube junction are straight tube-like.
The diameter of pump drainage storehouse and drainage tube straight tube-like junction is less than the diameter of pump drainage ball.
The pipeline of drainage tube and air supply pipe is each equipped with corresponding valve, thus realizing the adjustment of draining and gas pumping.
This utility model in use, is opened valve on drainage tube, is closed valve on air supply pipe, and under extraction suction function, pump drainage storehouse blocked by pump drainage ball, it may be achieved the normal extraction of gas; Open the valve on air supply pipe, the valve closed on drainage tube, at positive pressure, it may be achieved boring internal drainage.
This utility model solves existing descending mash gas pumping drilling hydrops and cannot get rid of, and affects the problems such as the normal extraction of gas.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
As it is shown in figure 1, a kind of descending boring drainage arrangement, including extraction system, air supply system, drainage system.
Extraction system is made up of drainage tube 2 and valve 4-1, and drainage tube 2 connects extraction negative pressure line.
Drainage tube 2 extends to bottom boring 1.
Air supply system is made up of air supply pipe 3, valve 4-2, and air supply pipe 3 connects high-pressure gas pipeline.
Drainage system is made up of drainage tube 2, pump drainage storehouse 5, pump drainage ball 6.
Pump drainage storehouse 5 and drainage tube 2 junction are straight tube-like, outside in horn-like.
Pump drainage storehouse 5 is outside is equipped with wire netting 7, is enclosed in pump drainage storehouse 5 by pump drainage ball 6.
The diameter of pump drainage ball 6 is more than pump drainage storehouse 5 straight tube-like and horn-like junction diameter, namely with the diameter of drainage tube 2 junction.
Opening the valve 4-1 on drainage tube 2, the valve 4-2 closed on air supply pipe 3, under suction function, pump drainage storehouse 5 blocked by pump drainage ball 6, it may be achieved the normal extraction of gas; Opening the valve 4-2 on air supply pipe 3, close the valve 5 on drainage tube 2, feed gases at high pressure, pump drainage ball 6 falls, it may be achieved bottom boring 1, hydrops is discharged by drainage tube 2.
