The Distribution Of Spontaneous Coal Seam In Qinshui Coal And Spontaneous Combustion Anlysis

Spontaneous fire is one of the main mine disaster. Spontaneous combustion of coal is not only a great waste of coal resources, resulting in economic and casualties, but also release large amounts of toxic and harmful gases, environmental pollution, destruction of ecological balance. Therefore, the impact of coal spontaneous combustion coal mine safety has become an important factor.Based on current coal combustion causes and mechanism of the natural level of spontaneous combustion of coal and coal Qinshui causes of spontaneous combustion. First, the basis of spontaneous combustion of coal, in theory, analysis of the impact Qinshui COAL SELF many factors. Secondly, oxygen method using chromatography on a few representative Qinshui coal coal was experimentally determined and the spontaneous combustion of its coal rank indicators and collected a total of Qinshui coal more than two hundred five cities coal samples of the above indicators, then these data for all of total sulfur in coal, ash, volatile matter, moisture content, the truth of the density of the five parameters on the relationship between oxygen uptake and nonlinear data to be regression, and the relevance of fuzzy mathematics test method to establish a mathematical model of a representative sample of the data to do a correlation analysis, and finally this paper Qinshui coal mine representative examples of coal and coal-forming environments from the perspective of spontaneous combustion of coal seam on the Qinshui analyzes the causes of ignition, the article that concluded as follows:total sulfur coal, oxygen uptake and water with the increase of oxygen uptake with the ash, volatile matter and the truth of the increase of the density reduced; oxygen uptake and total sulfur coal, ash, volatile matter are obviously related, but not with the truth of the density of water and no significant correlation. Qinshui 3 coal sulfur coal low, most difficult to spontaneous combustion coal, and 15 into the coal seam as environmental impact, resulting in higher sulfur content coal seam on the 15th, therefore, a considerable portion of 15 coal seam is easy to spontaneous combustion and coal combustion. The conclusions Qinshui Prevention of Spontaneous Combustion in Coal Seam provides a basis for decision making and technical support.
