Abstract

The invention discloses a coal spontaneous combustion and coal and gas mixed explosion test system. The system comprises a test furnace, an air storage tank, a gas storage tank, a gas chromatograph, atemperature display instrument and a temperature control heating system, the test furnace comprises a furnace body and a furnace body base, a circular observation window is arranged on a furnace doorof the furnace body; an air outlet of the air storage tank is connected with an air inlet of the furnace body; a gas outlet of the gas storage tank is connected with a gas inlet of the furnace body,an air flow control valve is mounted on the air inlet pipeline, a pressure gauge, a flow meter and a gas flow control valve are sequentially mounted on the gas inlet pipeline from the gas storage tankto the furnace body, and a gas collecting port of the furnace body is connected with the gas chromatograph; a thermal resistance sensor is installed in the furnace body and connected with a temperature displayer, and a pressure relief valve is installed at a pressure relief outlet of the furnace body. According to the invention, parameters such as critical temperature, gas quantity, explosion products and the like for causing coal spontaneous combustion to develop into gas and coal dust explosion can be measured, so that coal spontaneous combustion and coal and gas explosion laws are studied.

Description

technical field [0001] The invention belongs to the technical field of coupling disasters caused by coal spontaneous combustion and gas, and in particular relates to a coal spontaneous combustion and coal and gas mixed explosion test system. Background technique [0002] my country's coal resources are relatively rich, and coal resources are also a very important source of consumption in my country, accounting for about 60% of my country's primary energy consumption. In the process of coal mining, various accidents such as fire, coal and gas outburst, water seepage, gas explosion, coal dust, and roof collapse may occur. These disasters will not only cause the loss of coal resources, but also threaten the safety of underground workers. Life safety, destruction of production equipment, resulting in huge property losses. [0003] The natural fire of underground coal seams in coal mines will cause the loss of many resources. This is because the occurrence of fires is often acco...
