Water Bursting

Through applying the background values of aquifer derived from fuzzy clustering analysis, a fuzzy comprehensive estimation model was developed for quick recognition of mine water inrush. Based on the hydrological-chemical analysis data of water samples which water bursting sources were known in Liliu mining area, Shanxi province, this paper presented that the hydrological-chemical characters of different aquifer was different, and established a sort of fuzzy comprehensive evaluation models of discriminating coal mine water bursting sources in Liliu mining area. Applied to a production mine, the correct rate of water bursting source judged results by various methods was more than 70%. With the dispersion method and the method extracted from stepwise discrimination analysis to determine the membership degree and Model 3 the type determined by various factors, the correct rate of water bursting source with comprehensive evaluation of combination of two methods was higher respectively 94.5% and 93.3%. The fuzzy system can efficiently and accurately discriminate the resource of water inrush for an unknown sample, and provide the decision basis for the safety production of the coal mine.

Water Bursting

In order to further research the expansion of cracks in the rock during hydraulic fracturing, this paper theoretically analyzes the stress state of wall cracks. According to the effective stress criterion of Terzgahi, it gives the mechanical condition of the rock crack expansion. By Moore-coulomb's law, it analyzes the influence of the water pressure in the pores of space wall on the rock fracturing. On this basis, the hydraulic rock fracturing is applied to build physical experiment model of deep mining mine water bursting. By the methodology of combining the analysis of experimental results and theoretical analysis, it analyzes the change of water injection pressure in the hole with rock fracturing and the stress strain relations during rock’s uniform displacement change and loading. The experimental results show that in the process of the water pressure and vertical loading, the increasing fracture load on the rock, constantly produces, expands the cracks and fractures to instability; the mutual influence of water and pressure comes to be the major problem of deep mining rock fracture and mine water bursting.
