This paper analyzes on the main causes of the chain rupture accident of the drag-link conveyer, and puts forward some corresponding preventive measures.

Study on fault chains monitoring in regional power network by using a stochastic Petri net model;

FTA-based fault chains monitoring research in power system;

Cascading failure is one of the key factors resulted in large-scope blackouts,and can be properly characterized by the fault chain.

Based on the probability analysis model of fault chain of security science,the prediction index of middle segments of fault chain based on flow of network is presented to establish the fault chains,in which the cascading failure probability is quantified.

This paper introduces the characteristics of steel wire ropes used in the inclined-tunnel's lifting conveyance,analyzes on the main reasons of the rope-broken accident of hydraulic support in fully mechanized coal mining face,and advances some measures for preventing the accident.

Three parts of the visualization of the accident phenomenon, judging accident and handling accident are designed based on general process of accident anticipated plan.
