Fracturing detector under coal mine well

Abstract

The invention provides a fracturing detector under a coal mine well, belonging to an intrinsic safety type coal mine detector. A control computer is arranged at a safety area which is far away from a work coal wall at 1-2km. The control computer is connected with a wireless transmission substation; a wireless movement tester, a wireless gas tester and a wireless video camera are used for transmitting the collected detection data to the wireless transmission substation by a wireless signal, and the wireless transmission substation is used for transmitting the detection data to the control computer by a data cable and displaying the detection data; the control computer is connected with a fracturing pump detector by the data cable and to transmit the collected five real-time data of the fracturing pump to the control computer; and the operating personnel timely monitors the change condition of the work coal wall and the work state of fracturing equipment, and performs the necessary long-range control to the fracturing equipment.

Description

technical field [0001] The invention relates to the field of coal mine safety management, in particular to a fracturing detection device used in underground coal mines. Background technique [0002] In the coal industry, the risk of coal and gas outburst becomes greater and greater with the development of coal seam mining. At present, mines first drain the gas in the coal seam before mining. However, due to the soft quality of coal seam in some areas, traditional drainage The effect of the method is not obvious, and the gas in the coal seam cannot be effectively drained, and the hidden danger of coal and gas outburst cannot be eliminated to the greatest extent. The existing fracturing equipment is far away from the fracturing hole, generally about one kilometer, and the fracturing equipment usually transports the fracturing fluid to the fracturing hole through a high-pressure pipeline. During the working process of the fracturing equipment, the staff need to conduct regular...

AI Technical Summary

Problems solved by technology

During the working process of the fracturing equipment, the staff need to conduct regular inspections on the high-pressure pipeline and the equipment near the fracturing hole. Since the fracturing fluid is between 40-60MPa and the pressure is relatively high, the high-pressure pipeline is constantly subjected to liquid pressure during the working process. Therefore, the high-pressure pipeline may rupture and cause the risk of fracturing fluid leakage, and the maintenance workload of aging equipment is large; at the same time, the fracturing holes are currently arranged using empirical methods

During the working process of the fracturing equipment, the existing fracturing system requires staff to conduct regular inspections on the high-pressure pipeline and the equipment near the fracturing hole, which may cause high-pressure pipeline rupture and cause casualties of inspection personnel, which cannot guarantee mine production safety
