【摘要】：矿井通风系统的优劣直接关乎着整个矿井的安全稳定,每个生产矿井在发展生产到一定阶段后都必须对现有通风系统进行评估,针对所存在的问题,制定措施方案,适时进行优化改造,在工程中一般是根据实践经验在众多可选方案中选择一种直接进行改造，其实这样的做法带有很大的盲目性,而且未必能够达到预期效果。随着科学技术的发展,通风仿真技术的诞生,为矿井通风优化改造工作提供了新的研究方法,本文即采用先进、成熟的三维动态仿真系统即Ventsim,对双阳煤矿通风系统的优化改造进行研究,科学指导优化改造的进行。双阳煤矿从上世纪70年代建矿至今,生产水平已由第一水平转入第二水平,随着开采程度的不断深入,以及主采区逐渐向矿区西部发展，原有的通风系统已经不能适合现阶段的发展需要,通风改造势在必行,为提高改造工作可行性和有效性,以三维动态仿真模拟系统即Ventsim软件为主要方法手段,通过收集、测定、整理有关该矿井的基本数据资料为依据,构建了双阳煤矿仿真模型数据库,建立起双阳煤矿三维动态仿真模型，并对现状进行了模拟算,验证了所测通风参数的正确性,并提出了新建西翼风井的建议,对于西翼风井建成后的,维持主井和副井为进风井的基础上,对于中央风井、东风井、西翼风井在进回风的选择上,拟定了四种优化改造方案,以现有模型为基础,构建方案模型进行了模拟,并结合前人研究的有益经验,构建了通风系统改造方案评价体系,根据解算结果完善评价指标内容,并通过离差最大化法确定各指标的权值,最后利用灰色关联分析法,选择最佳方案,提高了优化改造的科学性,避免了盲目性,以期能够对通风优化改造工作起到一定的指导作用。
[Abstract]:The quality of mine ventilation system is directly related to the safety and stability of the whole mine. Every production mine must evaluate the existing ventilation system after developing to a certain stage. In engineering, we usually choose one of the alternative schemes directly according to the practical experience. In fact, this method has great blindness and may not achieve the desired effect. With the development of science and technology and the birth of ventilation simulation technology, it provides a new research method for mine ventilation optimization and transformation. The mature three-dimensional dynamic simulation system, Ventsim. studied the optimization and transformation of ventilation system in Shuangyang Coal Mine, and scientifically guided the optimization and transformation of the ventilation system in Shuangyang Coal Mine. The production level of Shuangyang Coal Mine has been changed from the first level to the second level since last century, and the main mining area has gradually developed to the west of the mining area. The original ventilation system is no longer suitable for the development needs of the present stage. Ventilation reform is imperative. In order to improve the feasibility and effectiveness of the retrofit, the 3D dynamic simulation system (Ventsim) is taken as the main method, which is collected and measured. According to the basic data of the mine, the simulation model database of Shuangyang Coal Mine is constructed, the 3D dynamic simulation model of Shuangyang Coal Mine is established, and the present situation is simulated to verify the correctness of the measured ventilation parameters. The suggestion of new west wing air well is put forward. For the west wing air well, on the basis of maintaining the main well and the auxiliary well as the air inlet well, for the central air well, the Dongfeng well and the west wing air well in the selection of the inlet and back air, four optimized retrofit schemes are drawn up. On the basis of the existing models, the scheme model is built to simulate, and combined with the beneficial experience of previous studies, the evaluation system of ventilation system reconstruction scheme is constructed, and the evaluation index content is improved according to the calculation results. The weights of each index are determined by the deviation maximization method. Finally, the grey relational analysis method is used to select the best scheme, which improves the scientific nature of the optimization transformation and avoids blindness. With a view to ventilation optimization and transformation work to play a certain role in guidance.
