A crawler-type coal-water-gas separation and metering conveying device

Abstract

The invention discloses a crawler-type coal-water-gas separation and metering delivery device, which is characterized in that it comprises a coal-water-gas separation device, a metering device, a delivery device, and is used to provide power for the coal-water-gas separation device, the metering device, and the delivery device. The crawler power device, the coal-water gas separation device, metering device, and conveying device are fixedly connected to the crawler power device; the coal-water gas inlet is connected to the coal-water discharge port of the borehole, and the coal-water gas is extracted After separation, the coal-water-gas separation device enters the metering device for metering and statistics, and then the separated and counted coal is transported out through the conveying device. The device of the present invention can move with the drilling position. During the process of hydraulic punching or hydraulic cutting It can be fully stirred and centrifugally rotated to separate the coal-water mixture, and the water with less coal content enters the drainage system, and then accurately measures the amount of coal flushing, and automatically transports it to the coal discharge system to meet the requirements of precise measurement.

Description

technical field [0001] The invention belongs to the field of coal mining, and particularly relates to a crawler-type coal-water-gas separation and metering conveying device. Background technique [0002] Gas disaster is one of the most important disasters in high gas mines and coal and gas outburst mines, and it is also one of the main bottlenecks restricting their production. In high gas, coal and gas outburst mines (or coal seams) without protective layer mining conditions, pre-draining coal seam gas in construction drilling is the most effective regional gas control measure, but for low permeability, high gas pressure, and high gas content In mines, penetration enhancement measures such as hydraulic punching and hydraulic slitting still need to be adopted to speed up the progress of gas treatment, solve the problem of low gas extraction efficiency, and achieve the purpose of pressure relief, permeability enhancement and rapid burst elimination. However, in the constructi...

Problems solved by technology

In high gas, coal and gas outburst mines (or coal seams) that do not have protection layer mining conditions, pre-draining coal seam gas by construction drilling is the most effective regional gas control measure, but for low gas permeability, high gas pressure and high content Mine still needs to adopt hydraulic punching, hydraulic slotting and other anti-permeability measures to speed up the progress of gas control, solve the problem of low gas extraction efficiency, and achieve the purpose of pressure relief, anti-permeability, and quick elimination of outbursts

However, during the construction process of hydraulic punching and hydraulic slotting, a large amount of coal-water mixture gushes out from the borehole. At this stage, the method of cofferdam is generally used to collect the amount of coal flushing, and after a certain period of precipitation, the amount of coal flushing is calculated by the volume method , and finally manually excavate and transport all the amount of coal flushing, the measurement is rough and cannot meet the requirements of precise measurement, and the measurement speed is slow, which cannot meet the rapid measurement requirements of the amount of coal flushing on site, and the cleaning workload is large, which increases the construction personnel. Work intensity, high transportation costs, time-consuming, poor working environment on site seriously affect the physical and mental health of construction workers

And the separation of coal and water is not complete, and the coal dust in the water will enter the underground drainage system, which will increase the load of the mud pump in the water tank and reduce its service life

If it is not cleaned, it will affect the section of the roadway, which is not conducive to ventilation and may cause the increase of gas in the roadway, which may threaten the safety of construction personnel on site
