The embodiment of the invention discloses a method, a device and a system for determining factors and trends influencing gas concentration changes. The method comprises the steps that historical datacorresponding to each factor in factors related to gas concentration in a coal face is obtained; simulating the variation trend of the ith factor according to the collected historical data of the ithfactor to obtain simulation data corresponding to the two types of variation trends; jointly inputting the simulation data corresponding to the j-type change trend and the historical data corresponding to the factors except the ith factor into a pre-constructed gas concentration prediction model to predict the gas concentration; calculating the correlation between the jth type change trend of theith type factor and the predicted gas concentration; and according to the correlation, determining factors influencing the gas concentration change and a change trend. By means of the mode, increase of the gas concentration can be avoided as much as possible, and therefore the life safety of workers is guaranteed.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of coal mine safety, and in particular to a method, device and system for determining factors and trends affecting changes in gas concentration. Background technique [0002] Gas accidents can be subdivided into gas explosion, coal and gas outburst, gas burning, gas suffocation, etc., among which coal and gas outburst is a very important gas accident. Generally, gas exists in the coal seam in the state of adsorption and dissociation, and will not outburst. But when the gas pressure balance in the formation is destroyed by mining work, it will lead to coal and gas outbursts. When coal and gas outburst occurs, a large amount of coal and rock mass will escape in a short period of time, accompanied by a large amount of gas gushing out. A large amount of high-concentration gas ejected will cause suffocation of underground personnel, making it difficult for workers to respond and escape...
