随机Petri网在煤矿水害处理流程中的应用研究

Application Study of Stochastic Petri Net in Treatment Process of Coal Mine Water Disaster

水害作为煤矿开采中的主要灾害之一,直接影响井下生产安全。为保障工作人员的生命安全,确保矿井生产的稳定性,提出了用随机Petri网对煤矿水害处理流程进行建模的方法,根据模型的可达标识图同构的马尔科夫链来对库所繁忙率和变迁利用率2个性能指标进行计算分析,为日后对疑似水害的处理流程进行优化提供了新思路。

As one of the main disasters in coal mining,water disaster directly affects the safety of underground production.In order to ensure the safety of the staff and the stability of the mine production,proposed the method of modeling the treatment process of coal mine with stochastic Petri net.According to the model reachable marking graph build the Markov chain to calculate and analyse its performance index,which provides a new idea for optimizing the treatment process of water disaster in the future.
