【摘要】：金属非金属矿山供水施救系统作为安全避险“六大系统”的一个重要环节,能够在矿山灾变急救时,通过为受困矿工提供充足的生活饮用水而达到抢险施救的目的。如何保证系统的优化运行依然是一个有待研究的课题。然而矿山井下条件错综复杂,具有诸多的模糊不确定性,如何准确地求解出矿山井下各个时刻以及未来某年供水施救系统水量需求和管网供水压力等主要参数,并实现供水施救系统应对紧急灾变的自动控制,是保证系统有效运行的关键。针对上述问题,介绍了金属非金属矿山供水施救系统在铜坑矿的建设情况以及模糊理论和Simulink仿真技术的理论与应用知识。在现有的模糊理论对城市供水优化配置的基础上,通过MATLAB软件的Simulink仿真工具箱,分别建立了供水施救系统各个环节的仿真模型,应用铜坑矿的实际数据对模型进行仿真检验。研究内容和取得的研究成果如下：首先,建立了基于模糊聚类理论和基于时间序列法的供水施救系统水量短期预测Simulink仿真模型,建立了基于模糊多项式理论和基于神经网络理论的水量长期预测Simulink仿真模型,结合铜坑矿的井下时用水量和年用水量资料进行了仿真预测分析；其次,建立了基于模糊T-S模型的供水施救系统管网工作状况的Simulink仿真模型,以井下监测监控系统对供水管网相关监测点的监测压力为数据库,仿真得到未来时刻各中段水箱出水压力,取得了较好的仿真结果。最后,建立了基于模糊PID控制的供水施救系统自动控制的Simulink仿真模型,为实现供水施救系统系统应对紧急灾变的自动控制打下了良好的基础。研究表明,基于模糊理论的Simulink仿真技术用于金属非金属矿山供水施救系统的优化运行是可行的,且符合矿山实际,能够为矿山安全生产提供更好的保障。图52幅,表10个,参考文献92篇
[Abstract]:As an important link of "six systems" of safety and avoiding danger, the water supply and rescue system of metal non-metal mine can reach the purpose of emergency rescue by providing sufficient domestic drinking water for trapped miners in the first aid of mine disaster. How to ensure the optimal operation of the system is still a subject to be studied. However, the conditions of underground mine are complicated and have many fuzzy uncertainties. How to accurately calculate the main parameters such as water demand of water supply and rescue system and water supply pressure of pipe network at every time and in a future year, etc. The key to ensure the effective operation of the system is to realize the automatic control of the water supply rescue system in response to emergency disasters. Aiming at the above problems, this paper introduces the construction of water supply and rescue system in copper pit mine, the theory and application of fuzzy theory and Simulink simulation technology. On the basis of the existing fuzzy theory for the optimal allocation of urban water supply, the simulation models of each link of the water supply rescue system are established by the Simulink simulation toolbox of MATLAB software, and the actual data of the copper pit mine are used to test the model. The research contents and results are as follows: firstly, the Simulink simulation model of water supply system short-term prediction based on fuzzy clustering theory and time series method is established. Based on fuzzy polynomial theory and neural network theory, Simulink simulation model of water quantity long-term prediction is established. Combined with the underground water consumption and annual water consumption data of Tongkeng Mine, the simulation and analysis are carried out. Secondly, Based on fuzzy T-S model, the Simulink simulation model of water supply rescue system pipe network is established. The monitoring pressure of underground monitoring and monitoring system to relevant monitoring points of water supply network is taken as the database, and the water outlet pressure of each middle section of water tank in the future is obtained by simulation. Good simulation results are obtained. Finally, the Simulink simulation model of automatic control of water supply rescue system based on fuzzy pid control is established, which lays a good foundation for automatic control of water supply rescue system in response to emergency disasters. The research shows that the Simulink simulation technology based on fuzzy theory is feasible for the optimal operation of water supply and rescue system in metal non-metal mines and can provide a better guarantee for mine safety in production. 52 figures, 10 tables, 92 references
