【摘要】：随着国家经济的快速发展,全国煤炭产量也达到了历史的最高点,各大矿局通过资源整合不断扩大矿井产量,吕临能化千万吨矿井的建设就是其中典型的例子。吕临能化千万吨矿井的建设主要是把庞庞塔矿与千万吨项目部整合为一个整体,通过扩大现有产量形成千万吨生产规模的现代化大型矿井。为了实现整合后的千万吨矿井能够有一个可靠、稳定的通风系统去保障安全生产,本论文针对庞庞塔矿与千万吨项目部现阶段的矿井通风系统运行情况进行分析研究。首先对庞庞塔矿与千万吨项目部通过750大巷连通为一个整体进行模拟分析与方案制定,找出各个方案的优缺点,然后通过对各个贯通方案进行全面比较和综合分析得出一个最佳的贯通方案。在750大巷以最佳方案贯通后,对庞庞塔矿与千万吨项目部的通风系统进行全面分析,验证贯通后千万吨矿井与750巷道风流的稳定性,找出通风系统中的不足,尤其是阻力过大区域和风量利用情况,提出合理的解决措施。在前两步的基础上,为提高整合后的千万吨矿井抗灾变能力,对庞庞塔矿与项目部采区独立通风、风机停转、全矿井的反风等进行仿真模拟分析。通过模拟的方法提前预测风机停转、反风后矿井通风系统的变化,从而制定应对井下火灾等突发情况的应急预案。通过对以上三个主要部分的分析研究,要使庞庞塔矿与千万吨项目部顺利贯通后的千万吨大型现代化矿井有一个稳定可靠的通风系统,为千万吨矿井以后的安全生产打下坚实的基础。
[Abstract]:With the rapid development of the national economy, the national coal production has also reached the highest point in history. The construction of the 10 million ton mine in Lv Lineng is a typical example. The construction of the 10 million ton mine in Lu Lineng is mainly to integrate the Pompangta mine with the 10 million ton project department as a whole. A modern large-scale mine with a production scale of 10 million tons by expanding its existing output. In order to achieve the integration of the 10 million ton mine, there can be a reliable and stable ventilation system to ensure the safety of production. This paper analyzes and studies the operation of ventilation system in Pompangta Mine and 10 million ton Project Department at the present stage. First of all, it simulates, analyzes and formulates the scheme of Pompangta Mine and 10 million ton Project Department through the connection of 750 roadways as a whole. Find out the merits and demerits of each scheme, and then through the comprehensive comparison and comprehensive analysis of each through scheme, we can get the best through plan. After the 750 alleys pass through with the best plan, The ventilation system of Pompangta mine and ten million ton project department is comprehensively analyzed to verify the stability of the ventilation flow in the ten million ton mine and 750 roadway after the completion, and to find out the shortcomings of the ventilation system, especially in the area of excessive resistance and the utilization of air volume. On the basis of the first two steps, in order to improve the disaster resistance ability of the integrated ten million ton mine, the ventilation of Pompangta mine and the mining area of the project department are independently ventilated and the fan stops running. Through the method of simulation, the change of mine ventilation system is predicted in advance after the fan is stopped and the ventilation system is changed after the reverse air. In order to formulate emergency plans to deal with underground fire and other emergencies. Through the analysis and study of the above three main parts, A stable and reliable ventilation system will be established between Pompangta Mine and the ten million ton project department, which will lay a solid foundation for the safety production of the ten million ton mine.
