On basis of an analysis of the geological condition,law of gas outburst and materials about coal-and-gas outburst,this paper summarized the characteristics associated with coal-and-gas outburst of Zhaogezhuang Mine and studied the factors controlling coal-and-gas outburst such as stress,coal structure and gas pressure,content of gas.Then.based on a comparison of effects of in-situ stresses,coal structure and gas on coal-and-gas outburst of Zhaogezhuang Mine,the paper concludes that the major geologicaI factors that control coal-and-gas outburst of Zhaogezhuang Mine are in-situ stresses and coal structure.

The paper presented assessment of sealed fire states in underground coal mines by so-called “fire characteristic”, which graphically described tendencies of fire gas components - oxygen, nitrogen, carbon dioxide, carbon monoxide and hydrocarbons - in time
As longwall caving mining method prevails rapidly in China coal mines, amount of gas emission from longwall faces and goaf area increased significantly. Using traditional gas drainage methods, such as drilling upward holes to roof strata in tailgate or dr
Based on the exploration of the engineering geology and the rock mechanics testing, limit equilibrium analysis method was adopted to calculate the stability of the Huogeqi Copper Mine slope, the results show that the original slope angle is too conservati
The effect of duct surface character on methane explosion propagation was experimentally studied and theoretically analyzed. The roughness has effect on methane explosion propagation. The flame propagation velocity and the peak value pressure of methane e
Based on cooperative theories and analysis of characters of safety and production in coal mines, discussed the relationship and function of cooperative development between safety and production and established a basic cooperative development model.At the
An experience formula of expansive strain and stone taken from a foundation pit of Hongshanyao Project (HSYP) in Nanjing was described. It is clear that the curve of expansive strain-water content is a logarithm. In the meantime, the relation of expansive
Movement and deformation of underground rock include vertical dislocation and horizontal deformation,and the energy released by mine earthquake can be calculated basing on deformation energy.So put forwards the prediction for degree and spread of mine ear
Mathematical morphology is widely applicated in digital image procesing. Vari-ary morphology construction and algorithm being developed are used in deferent digital image processing. The basic idea of mathematical morphology is to use construction ele-men
The main purpose of the research is to study the influence on shallow ground water by heavy metaI in polluted river.In the lab-scale experiment polluted rivers were simulated by domestic sewage.and three kinds of natural sand were chosen as infiltration m
Analyzed the rule of the Water Flowing Fractured (WFF) zone\'s development during the fully mechanized top coal caving. Six influence factors of WFF\'s height were selected, viz. mining thickness, base rock thickness, dip angle, uniaxial compressing s
