通过对煤炭企业生产经营特点的分析，建立了适合于煤炭企业的动态投入产出模型．将巷道作为一种自产产品纳入投入产出表中，并在建模过程中充分考虑了地质条件因素的影响，给出了一种量化地质条件的方法，使投入产出模型更加符合煤炭企业生产实际，为煤炭企业的生产经营计划及决策提供了有力的定量分析工具．同时，对今后投入产出技术在煤炭中的应用也具有一定的理论及现实意义． Through the analysis of the characteristics of coal production and operation, a dynamic input-output model suitable for coal enterprises is established. The alleyway as a self-produced product is included in the IO table. In the process of modeling, the influences of geological conditions are taken into full consideration. A method to quantify the geological conditions is provided to make the IO model more in line with the coal enterprises The actual production provides a powerful quantitative analysis tool for the production and operation planning and decision-making of coal enterprises. At the same time, it also has certain theoretical and practical significance for the application of input-output technology in coal in the future.
