Application of phase space reconstruction and v-SVR algorithm in predicting displacement of undergro
A new method for predicting the trend of displacement evolution of surrounding rock was presented in this paper. According to the nonlinear characteristics of displacement time series of underground engineering surrounding rock, based on phase space recon
Computerized geological models are the basis of modem mine design, planning and production. A sound, validated geological model is essential to the success of a mining project. However, due to the complexity of geology surrounding deposits, geological mod
Based on hydro-geological of Qilongcun landfill, the transportation mathematical model of leachat was established. The boundaries conditions and replenishment of model were determined. The leachate COD density and the water level were simulated, and the m
Typical failure types of slopes of expansive soils are divided to two kinds: slip in surface layer and slip in shallow layer. Based on total strength law of expansive soils, the relationship between its water content and shear strength inculding cohesion
By the microseismic (MS) monitoring system of Sanhejian Coal Mine, the detailMS activity rules in the entire mining process of 9202 strong rockburst working face werestudied, following main conclusions were obtained. (1) The strong correlation between MSa
At present the bored construction method is one of the main construction methods of metro and tunnel construction in China. The empirical estimated formulas of tunnel ground surface settlement using the bored construction method were obtained,combining th
The coal hydrogenation reaction process is simply considered as three steps. In the first step, the smaller molecules associated with coal structure units are released as some gases and water in the condition of solvent and heating. In this step, some wea
Scale effect is one of the important aspects in the macro mechanical parameters\' research of rock mass, from a new point of view, by means of lab and field rock mechanics test, establishment of E~Vp relation, classification of engineering rock mass, nu
On the basis of ANSYS finite element model(FEM) software, the deep-leve lrockburst in Fuxin coalfield was simulated numerically. Based on Haizhou Mine and Wulong Mine as two typical deep-level rockburst examples in Fuxin coalfield, the rules and character
