Mine ventilation system is a multi-variable complex system, in which a roadway may result in changes in the parameters and their relative Boundary more than the wind tunnel and even the whole network of air volume changes; On the contrary, in order to make a certain amount of a wind tunnel to reach a certain required value, but also by a number of roadways in other regulatory measures taken to achieve.

矿井通风系统是一个多变量的复杂系统，其中一条巷道参数的改变可能导致与其相关的多条巷道甚至整个风网的风量发生变化；反之，要想使某一条巷道的风量达到某一要求值，也可以通过在其它若干条巷道内采取调节措施来实现。

Based on the production and supply of the coal industry in China, the capital construction projects and their investments in coal industry are investigated. Based on relative data from 1991 to 2000, a system dynamics model for coal suply and investment is formulated under the requitement of coal demand for building a well-off society in an all-round way. Meanwhile, policy analysis of investment for the throughput of state-owned colliery is made and the satisfied results are also obtained.

本文根据我国煤炭生产和供应的实际情况，对全国煤炭工业矿井基本建设项目及其投资情况作了调查，以1991至2000年之间的历史数据为依托，建立了全面建设小康社会期间煤炭需求作用下的全国煤炭生产供应系统动力学模型，并对全面建设小康社会期间国有煤矿供应能力开展了煤炭投资政策分析，取得了一些有意义的结果。
