Analyze On Models And Application Of Dynamica Overall The Dangerous Of Gas Explosion On Full Mechanized Coalface

The gas emission shows obvious varieties because of the increase of output and height on digging which influence the safety production searously.In order to master the dangerous of gas on full mechanized coalface on time and prevent the gas explosion accidents,The main purpose of research on the dangerous of gas explosion is to make clear about the logical relations among all affect factors and the degree of gas explosion.This thesis discuusses the construction and compositions of gas explosion on full mechanized coalface based on the Accident_causing Theory,makes an overall analyze on four aspects of gas explosion on full mechanized coalface:gas conditions,man,merchine and management.Builds up a set of evaluate index which could show the relations among all affect factors and the nature of gas systerm.Considering the dynamica caractor of gas explosion system,this article uses Grey connection degree method to make sure the Grey connection degree between the second and goal layers,and then carries on Analytic Hierarchy Process,based on the results of AHP and standard sample,a gas explosion analyze model on full mechanized coalface is designed with procedure of BP neural network to assess the grade of four aspects of gas explosion.At last,the closest factor(gas emission) on a concrete full mechanized coalface is forecasted accurately with the model of BP neural network.The purpose of this thesis is to connect the argumentation of dangerous,the scientifical assessment of prevention ability of gas systerm on full mechanized coalface and the establishment of safety secure institutions tightly.To offer a gist for the controlling systerm of gas explosion accidents as well as realize modern management centerned with prevention of accident.
