Instability Mechanism of Extraction Structure in Whole Life Cycle in Block Caving Mine
Published 2021-01-01“…The investigation in the mine site shows that the extraction structure often presents the law of repeated instability. In order to reveal the mechanism of repeated instability of the extraction structure, the whole life cycle of extraction structure can be divided into three stages, namely, the formation stage of extraction structure, the undercutting stage without initial caving, and the ore caving and drawing stage. …”

DYNAMIC SIMULATION AND EXPERIMENTAL STUDY ON RIGID-FLEXIBLE COUPLING OF SHEARER
Published 2019-01-01“…The results show that the stress value and the load fluctuation value of the rocker joint pin are larger when the flexible deformation of the rocker arm is considered, which indicates that the flexible deformation of the rocker arm increases the vibration impact of the whole machine and reduces the strength of the shearer And the life expectancy of the shearer’s rocker pin, the fatigue life is 1.738×10~6 times, which proves the feasibility of the experimental method and provides the theory for the selection of the rocker pin in the actual working condition.…”

Research on network attack analysis method based on attack graph of absorbing Markov chain
Published 2023-02-01“…Existing intrusion path studies based on attack graph lack consideration of factors other than basic network environment information when calculating the state transition probability.In order to analyze the security of target network comprehensively and reasonably, a network attack analysis method based on attack graph of absorbing Markov chain was proposed.Firstly, a state transition probability normalization algorithm based on vulnerability life cycle was proposed based on attack graph.Secondly, the attack graph was mapped to the absorbing Markov chain and the state transition probability matrix was given.Finally, the state transition probability matrix was calculated to comprehensively analyze the node threat degree, attack path length and expected impact of the target network.The results show that the proposed method can effectively analyze the expected influence of node threat degree, attack path length and vulnerability life cycle on the whole network, which is helpful for security research personnel to better understand the security state of the network.…”

Establishment and Implementation of Sponge City Monitoring System— A Case Study of Zhenjiang
Published 2022-01-01“…In order to effectively deal with urban water pollution and waterlogging,China proposes the concept of sponge city for stormwater management,which takes the control rate of total annual runoff,urban non-point pollution control,and urban rainstorm and waterlogging prevention as evaluation indicators to comprehensively improve the water resources,water security,water environment,and water ecological quality of cities.In the process of sponge city planning,construction,operation,and maintenance,it is necessary to establish a complete online monitoring system to assist the whole life cycle management of the sponge city construction.With Zhenjiang city listed in the first batch of pilot sponge cities in China as an example,a multi-level and organically nested sponge city monitoring system is constructed,and it mainly monitors rainfall,underlying surface,land area (sponge facilities,project sites,drainage zones),rivers and lakes,and basins.In addition,its monitoring indicator,distribution principle,monitoring frequency,as well as selection,recognition,and effective utilization of data are specified.The construction and implementation of the sponge city monitoring system are of great theoretical significance and application value for evaluating the construction and operation optimization of sponge cities,strengthening urban waterlogging prevention and control,and systematically promoting sponge cities in the whole area.…”
