摘要：
The length of the pre-splitting crack is an important parameter in underground mine deep-hole blasting, and experience and engineering analogy methods are used commonly, but they seldom have scientific and theoretical basis. In this paper, the mature numerical analysis software - ANSYS/LS-DYNA was adopted, the different lengths of pre-splitting crack were simulated. In the filling body, the corresponding maximum blasting vibration velocity and stress are obtained by numerical simulation when the maximum initiation section blasted. The corresponding regression formulas are obtained by using the least square method, and the optimal length of the pre-splitting crack is 12 m through the calculation. Proved by practice, this method to get the length of the pre-splitting crack is scientific and effective, can be extended in other similar blasting engineering.

摘要：
Bridge erecting machine has been widely used nowadays with its efficiency, while just as a coin has two sides, it also brings problem. If a rollover happens, it will lead to equipment damage, casualties or other disastrous accidents. How could technicians take measures to prevent accidents as efficiently as possible? Question remains unsaved. Based on the analysis of “10.26” bridge erecting machine tipping accident, this paper gives a qualitative analysis on the accident by using fault tree analysis. Firstly, fault tree diagram for the bridge erecting machine tipping, namely the causal and generalization relation between events is formulated. All the basic events that influence the way and the degree of the accident are identified, and these can be ascribed to the following three aspects: manufacturing defect, personnel operating error and management oversight. In terms of management oversight, the responsibility of construction unit, safety supervision department and supervision unit are of great importance. Secondly, combining the minimal path set with the structure importance, we conduct a qualitative analysis on the personnel casualties resulted from the accident, thus seek critical approaches to accident prevention. Finally corresponding safety control measures are put forward. It is noteworthy that the approach can be applied in the similar accidents entirely.

摘要：
August 12, 2011, a locomotive runaway has happened on the local railway named Xihe railway of a certain city, it led to a death of an older person and serious damage of four automobiles. The causing factors of the runaway accident have been comprehensively analyzed, which respectively include four aspects: human, machine, environment and management. By using the principle of fault tree analysis (FTA), the locomotive runaway accident fault tree has been set up after the accident investigation. Based on the corresponding formula, the authors have calculated the structure importance coefficient of each basic event. By analyzing the causation of the events, the minimal path sets have been obtained, and the order of the structure importance has also been obtained. Through the above analysis, the reasons of this accident have been analyzed systematically and the corresponding safety countermeasures have been proposed. The thesis can provide reference for prevention of similar accidents. (C) 2012 Authors. Published by Elsevier Ltd.

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.
