Embodiment Construction

[0017] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0018] The invention provides a gas outburst barrier system for a coal mine excavation face.

[0019] Such as figure 1 As shown, in this system, the multi-mode signal sensor 1 is connected to the signal integrated processor 2, the signal integrated processor 2 is connected to the sound and light alarm device 3, the start switch 4, and the power supply 7, and the gas generator 5 is connected to the semi-flexible airbag 6 is connected, and the start switch 4 is connected with the gas generator 5.

[0020] Among them, the multi-mode signal sensor 1 includes more than four kinds of signal sensing elements, which are used to collect the temperature, humidity, atmospheric pressure, gas concentration, and gas pressure signals in the working space and inside th...

Abstract

The invention provides a coal mine driving working face gas outburst obstruction system, and belongs to the technical field of mining safety. The coal mine driving working face gas outburst obstruction system comprises a multi-modal signal sensor, a signal integrated processor, a sound-light alarm device, a starting switch, a gas generator, a semi-flexible air bag and a power supply. The multi-modal signal sensor detects parameters including temperature, humidity and gas concentration in the driving working space, signals are transmitted to the signal integrated processor for processing in real time, when signals are abnormal, the signal integrated processor outputs an early warning signal to the sound-light alarm device and the gas generator, the gas generator generates a lot of inert gas quickly to make the air bag inflate, the tunnel cross-section is obstructed, and the air bag plays a role in obstructing and buffering eruption of gas and coal rock solids towards the digging space. The coal mine driving working face gas outburst obstruction system protects life safety of workers in first time in case of emergency, and plays a buffering role in the coal and gas outburst accident, and can buy people time to escape safely.

Description

technical field [0001] The invention relates to the technical field of mining safety, in particular to a gas outburst barrier system for a coal mine excavation face. Background technique [0002] Coal and gas outburst has always been one of the major disasters in my country's coal mines. According to statistics, more than 70% of major coal mine disasters in my country are gas accidents, and the death toll accounts for about 40% of the total death toll in coal mine accidents. With the increase of coal mining depth, the ground stress and gas stress increase, and the coal body is more likely to be unstable under the action of high stress. The result of the joint action of various factors has led to the occurrence of gas dynamic phenomena in mines and mining areas that have not previously outburst. [0003] When coal and gas outbursts occur, the first task is to let the staff quickly evacuate the dangerous area to ensure the safety of the staff, and the second is to prevent sec...
