中文摘要：

基于系统动力学理论,采用因果图对煤矿生产物流系统安全性与效率性影响要素之间的作用关系进行分析,构建了煤矿生产物流系统安全性与效率性SD模型,并对系统安全性与效率性作用机理进行定量分析,最后通过仿真分析得出：安全资源的大量浪费为煤矿企业加重了负担,制约了企业安全水平的发展;增加安全投入与安全资金合理匹配,有利于煤矿企业促进系统安全性与效率性协同发展.研究结果对强化煤矿安全生产水平具有一定的借鉴意义.

英文摘要：

Based on system dynamics theory, the cause diagram is used to conduct analysis on the relationship between in- fluence factors of the system safety and efficiency, the SD model of system safety and efficiency is constructed, also the func- tion mechanisms of the system is quantitatively analyzed and finally based on the simulation analysis it is found out that the waste of safety resources increases burden of coal mining enterprises, which restricts the development of enterprise safety lev- el; the increase of safety input and reasonable match of safety funds will help to the coordinated development of system safety and efficiency in the coal mining enterprises and it has a certain reference significance to strengthen the safety production level of coal mine enterprises.
