Empirical analysis on contribution share of safety investment to economic growth: A case study of Chinese mining industry
Mining industry Production safety indexes Economic growth model Contribution share of safety input toeconomy growth
2012/3/19
Insufficient investment in safety is one of the most important reasons which lead to frequent accidents in Chinese mining industry. Safety input has long been regarded as a ‘sunk cost’, lacking output...
Analysis on rock burst danger when fully-mechanized caving coal face passed fault with deep mining
Rock burst Microseism monitoring system Fault Numerical simulation
2012/3/27
When fully-mechanized caving face passed fault, rock burst accidence easily occurred. The SOS microseism monitoring system was applied to monitor the microseismic activities all time occurred in the c...
Hybrid data mining-regression for infrastructure risk assessment based on zero-inflated data
Classification tree Risk assessment Regression Zero-inflated
2012/4/22
Infrastructure disaster risk assessment seeks to estimate the probability of a given customer or area losing service during a disaster, sometimes in conjunction with estimating the duration of each ou...
Experimental investigation on the seepage law of pressure-relieved gas under the influence of mining
Pressure-relieved gas Seepage Stress distribution Simulation experiment
2012/3/27
The stress distribution characteristics of the coal seam floor and the variation of pressure-relieved gas seepage velocity along with working face being advanced were studied experimentally. According...
Stability of workface using long-wall mining method in extremely thin and gently inclined iron mine
Long-wall method Extremely thin Iron mine Surrounding rock Stability
2012/3/27
Long-wall mining method has its own advantages, such as small mining-cutting ratio, the simple technique of recovery and high level of mechanization, which is the optimal method used to mine gently in...
Mining disturbance effect and mining arrangements analysis of near-fault mining in high tectonic stress region
Near-fault mining Mining disturbance effect Coulomb failure stress increment Mining arrangement Dynamic disaster risk
2012/3/27
Dynamic disasters can be easily induced by mining disturbance in the tectonic stress concentration region near the fault. Based on the fault Coulomb failure stress criterion, a dynamic Coulomb failure...
Experimental research on the variational characteristics of vertical stress of soft coal seam in front of mining face
Soft coal seam Mining face Vertical stress distribution Layered characteristics Experimental research
2012/3/28
Permeability of coal seam is extremely sensitive to the in situ stress loaded. The techniques of ‘‘Pressure relief’’ have been proved significantly effective in practice to improve the gas permeabilit...
