I. Implementation Background <br /> In order to meet the support and support of roadway support in a certain coal mine, meet the coal seam water injection, reduce the generation of coal dust, reduce the impact ground pressure, coal and coal bed gas outburst and spontaneous combustion. The workshop used the emulsion pump box for the erection of the bracket. The pump was used for multiple purposes, which contributed to cost savings for the enterprise.
Second, the design plan <br /> With the continuous increase of the mining depth of our mine, the pressure of the roadway is increasing, the support of the mining roadway and the water injection of the coal seam become particularly important. At present, our mine uses "U" beams, roadway supports, Roadway support is supported by hydraulic sheds, single pillars, etc. This requires a large amount of high-pressure emulsion to complete the installation and ensure the safety and quality of the roadway; water injection into the coal seam, pressurized water and aqueous solution are injected into the coal body, and moisture is added to change the coal Physical and mechanical properties, can reduce the generation of coal dust, can also reduce the impact of ground pressure, coal and coal bed gas outburst and spontaneous combustion. The erection of the support uses emulsion, the coal seam uses water solution, and both use the BRW125 / 31.5 pumping station. According to this phenomenon, the workshop remodeled and designed a multifunctional pumping station, which can It meets the support and support of the roadway support, and can meet the coal seam water injection, which saves a set of equipment, saves space and manpower, and has a very good effect.
Third, the main content and innovation
The BRW125 / 31.5 pumping station consists of two pumps and a RX1500 pump box. We remodeled the RX1500 pump box, welded the box body and divided it into two. One side was used to hold the emulsion and one side was used to hold the aqueous solution. The other side of the pump box was opened according to the principle of liquid supply. Φ51 suction joint, Φ32 unloading joint, Φ25 high-pressure liquid supply joint are welded to the holes, and the three holes of the emulsion tank and the aqueous solution tank are respectively connected to the corresponding joints of the pumping station by high-pressure hoses, tees, and stop valves.
When the roadway is supported, close the three shut-off valves of the water tank. The pump station sucks the emulsion and pressurizes it to set up the shed support and the roadway branch. When the coal seam is filled with water, close the corresponding three shut-off valves of the emulsion tank. The station draws in the aqueous solution and pressurizes it for water injection into the coal seam.
We have renovated a pumping station and used one pump for multiple purposes, which not only met the roadway support, but also achieved coal seam water injection.
4. Completion time, effect analysis, and popularization and application <br /> The project was completed in March 2014. At present, the multi-function pumping station has been used in multiple mining tunnels in our mine. The problems of management, operation, personnel, etc. have effectively ensured the support of the roadway, reduced the generation of coal dust, and reduced the impact ground pressure, coal and coal bed gas outburst and spontaneous combustion.
