摘要：
The "338"tin mine located on Baisha Town of Changning City in Hunan Province, the kaists crevasse grit-filled tin deposit, had a serious water-penetration and putty-gushing accident in 2# admission passage of 95m center-section, causing five-person dead on May 22, 2005. By analyzing the ore deposit hydrology geological data, the mining technology and the geologic structure, this paper concludes that the blasting during mining tunneling process destroying the aquifuge of karsts pipeline is the immediate cause of this accident, and the continuous raining increasing the hydrodynamic pressure in karsts pipeline is the important cause of this accident. This article has comprehensively analyzed the mechanism of water-penetration and putty-gushing, and carried on preliminary discussion on the geological forecast technology and the control technology of. the water-penetration and putty-gushing disaster.

摘要：
Ventilation has been proved to be a main method, to eliminate radon and radon daughters of uranium mine. At present, in the uranium mine ventilation system, several problems are existed as follows: jumbled systems, serious air leakage, series ventilation, low effective air volume rate and unqualified rate of concentrations of radon and its daughters and so on. According to the practical rectifications of uranium mine ventilation system, some summarizing experiences of improving measures are presented in the paper, which include investigating radon source, controlling the direction and size of radon seepage, exerting the inhibition effects of ventilation, reducing air leak, increasing the ability of radon dilution and establishing complete ventilation system. In addition, a practical example is analyzed to introduce safety assessment method for uranium mine ventilation system.
摘要：
The strip mine truck transportation scheduling system is of uncertainty attribute which is involved to fuzzy parametric problem such as transportation path, production process and shoveling-transportation-crashing equipment under environment. Because of fuzzy programming depending on complex degree of member function of fuzzy coefficient, it cannot to be solved through transforming clear math programming problem, anymore, it is difficult to get optimal solution with the classics optimization algorithm. This parper has constructed immune particle swarm optimization algorithm by integration of excellent performance of immune algorithm and particle swarm optimization algorithm, thenafter, it is set up corresponding fuzzy programming model by its uncertainty attribute parametric of truck transportation shceduling system and fuzzy judgment decision criteria, finally, optimization problem of transportation scheduling system under fuzzy environment is to be solved well. It is not only to solved effectively optimization problem of truck transportation scheduling system under fuzzy environment, but also it provides important reference value for. optimization And decision-making problem of other complex system.
