Water-inrush self-saving device for coal mine

Abstract

The invention relates to a water-inrush self-saving device for a coal mine, belongs to the technical field of rescue equipment for coal mines, and provides a water-inrush self-saving device for a coal mine, which is simple in structure, is convenient to operate, and when a water-inrush accident happens, can be used for carrying out self-saving, supplying oxygen to a help-seeking person and prolonging escape time. According to the adopted technical scheme, one side of a basal plate is provided with straps; the other side of the basal plate is provided with a high-pressure hermetic cavity; the high-pressure hermetic cavity is filled with liquid oxygen; the bottom of the high-pressure hermetic cavity is provided with a gas charging nozzle; the top of the high-pressure hermetic cavity is provided with a pressure reducing valve; the pressure reducing valve is connected with a diving mask through a gas conveying pipe; the gas conveying pipe is provided with a control valve; the diving mask is placed in an object storage bag; the object storage bag is fixedly arranged at the top of the basal plate; further, the object storage bag is provided with a zipper. The water-inrush self-saving device for the coal mine is widely used for the water-inrush self-saving of the coal mine.

Description

technical field [0001] The invention relates to a coal mine permeable self-rescue device, which belongs to the technical field of coal mine rescue equipment. Background technique [0002] In recent years, there have been many water seepage accidents in coal mines across the country. Due to the complex underground situation and the difficulty of rescue, many underground coal miners died or were trapped underground, and the safety production situation is still severe. The reasons for water seepage accidents and casualties are as follows: some coal mining enterprises do not have a strong awareness of safety precautions, pay more attention to production than safety. The company’s water prevention and control measures are not in place, and it is not necessary to explore in case of doubt, to explore first and then to dig, and to take measures to detect and release water in accordance with the "Regulations on Water Prevention and Control in Coal Mine", which leads to the connection...

The reasons for water seepage accidents and casualties are as follows: some coal mining enterprises do not have a strong awareness of safety precautions, pay more attention to production than safety. The company’s water prevention and control measures are not in place, and it is not necessary to explore in case of doubt, to explore first and then to dig, and to take measures to detect and release water in accordance with the "Regulations on Water Prevention and Control in Coal Mine", which leads to the connection between the excavation face and the abandoned well or the old pond in the goaf. Water flooding accidents were caused; some coal mining enterprises did not have strict on-site safety management, leading cadres of the coal mines did not go to the mine to lead shifts as required, and could not organize personnel to evacuate in time after the flooding occurred, resulting in casualties; some coal mines illegally organized production
