基于采选充一体化的煤矿生产物流系统优化理论及建模研究

The new production model of integration of coal mining, gangue separation and solid backfilling is a good way to solve the problems of “three under”(under building, under railway, under water), solid waste emissions and ground surface subsidence which are caused by traditional caving method. Comparing to traditional caving method, the new production model is added some subsystems for washing and separation of coal gangue, crushing, and backfilling in the limited underground space, which makes the complex coal mine production logistics system affected by many kinds of random factors face greater challenges. Therefore, integrating multiple theories of systems engineering, modern logistics system and coal mining, the project employ the methods of theoretical analysis, modeling, simulation and field test and focuses on the problems of coal mine production logistics system in the new production model. Firstly, we will analyze the layout, technological process and technical parameters of subsystems related to the coal mine production logistics system, and the interaction relationships of these subsystems. Secondly, we will study the factors of the coal mine production logistics system on efficiency, safety, cost and other aspects and how to measure these factors. Thirdly, we are going to construct a model to optimize the node location and space layout of coal mine production logistics, a model to forecast freight volume of production logistics and a multi-objective decision optimization model aiming at the lowest cost and energy consuming, the high efficiency and safety for production logistics. Finally simulation and field test will be carried out on the basis of former research. Then, the research results will enrich the technique and theory of the new production model of coal mining, expanding the theory of coal mine production logistics systems, and promote the popularization and application of green mining of coal mine based on the new production model of integration of coal mining, gangue separation and solid backfilling.

煤矿井下采选充一体化开采系统环节众多、作业复杂、受多种随机因素影响，目前大部分相关研究都集中于采选充生产相关的机械设备研发与工艺流程设计等，而探究煤炭井下采选充一体化条件下生产物流系统的研究较少。本课题基于系统工程、复杂系统理论以及矿山开采等基础理论，采用系统建模与仿真的方法开展了如下几个方面的研究：（1）对比分析了传统开采方法与采选充一体化开采方法下煤矿井下生产物流系统的组成、关键环节及影响因素，构建了传统煤矿开采和采选充一体化开采条件下的井下生产物流系统优化模型，可以有效识别系统瓶颈，提高系统生产效率。（2）构建了采选充一体化煤矿井下生产物流系统效率仿真模型，识别影响生产物流系统效率关键因素并预测系统效率水平变化趋势，分析了采选充一体化生产掘进、采煤、洗选、充填主要环节对生产水平的实际影响率。（3）构建了采选充一体化煤矿井下生产物流系统碳排放系统动力学仿真模型。（4）针对采选充一体化开采方法技术采纳意愿问题，考虑补贴、惩罚和信息共享三种政策及其组合对煤企进行新技术采纳的影响，构建政府与煤矿企业关于采选充一体化建设的演化博弈模型，提出了推动采选充技术采纳的最优政策组合。（5）进一步拓展了煤炭企业低碳生产相关研究，分析了煤炭生产侧与消费侧碳排放强度的影响因素；探讨了煤炭企业技术创新与环保信息披露水平的关系及其对财务绩效的协同影响。.本项目的研究成果为采选充一体化开采井下生产物流系统碳排放、效率等多因素优化提供了模型和方法，也为采选充绿色开发方法推广策略提供重要参考，进一步丰富井下采选充一体化条件下的煤矿生产模式理论体系和煤矿生产物流理论体系，有利于促进煤炭企业绿色低碳高效生产。
