【摘要】：自改革开放以来,随着我国经济的飞跃发展,许多企业和工厂规模不断扩大和经济效益的显著提高,所需的原材料和生产出的产品数量也在不断增长。为了适应企业的发展格局,修建了供所属单位运输货物的铁路专用线。据统计,煤炭铁路专用线在铁路专用线中所占比例较大,数量已达上千条,公里数超过一万多公里,承载着大量货物运输任务,是我国铁路运输网乃至交通运输网的重要组成部分。煤炭铁路专用线大多处于偏远地区,存在设备老旧失修、工作人员素质较低以及安全管理落后不合理等问题,安全状况令人堪忧。对煤炭铁路专用线进行科学合理的安全评价,找出存在的安全隐患,减少甚至消除安全风险,对煤炭铁路专用线的发展具有重要的现实意义。煤炭铁路专用线是一个复杂的系统,运输业务包括了行车组织、机务作业、工务维修、电务维修、车辆检修五个大的门类。论文根据生产经营单位安全评估的原理和原则,主要从这五个方面阐述这些运输业务安全现状,存在的危险有害因素,提出相应的对策和建议。除了对上述各项业务进行安全风险分析,论文分析了安全管理中存在的风险因素,明确安全管理的不足之处,将为提高安全管理水平,奠定重要的制度和执行基础,以及研究了煤炭铁路专用线两个突出的问题,即平交道口问题和线路养护维修周期确定问题。根据上述对煤炭铁路专用线安全影响因素的分析,建立与我国煤炭铁路专用线安全现状相匹配的安全评价指标体系,采用模糊层次分析法给出各指标的权重,运用动态模糊理论建立铁路专用线安全评价模型,计算各级指标的模糊值、评价等级,得到指标的发展趋势,形成铁路专用线动态评价结果,为专用线安全管理提供参考和依据。最后,以赤大白铁路专用线为例,对其安全性进行评价来验证模型的可行性。
[Abstract]:Since the reform and opening up, with the rapid development of China's economy, the scale of many enterprises and factories have been expanding and the economic benefits have been improved significantly, and the number of raw materials and products produced has also been increasing. In order to adapt to the development of enterprises, the construction of a unit for the transport of goods dedicated railway lines. According to statistics, coal railways account for a large proportion of the special railway lines, with a number of more than 1,000 and more than 10,000 kilometers, carrying a large number of cargo transport tasks. It is an important part of railway transportation network and even transportation network in China. Most of the special coal railway lines are located in remote areas, the equipment is old and out of repair, the quality of the staff is low, and the safety management is backward and unreasonable, so the safety situation is worrisome. It is of great practical significance for the development of coal railway private line to carry out scientific and reasonable safety evaluation to find out the hidden danger of safety and to reduce or even eliminate the safety risk. The coal railway special line is a complex system, the transportation business includes the traveling organization, the locomotive operation, the public works maintenance, the electrical service maintenance, the vehicle maintenance five big categories. According to the principle and principle of safety assessment of production and management units, this paper mainly expounds the present situation of these transportation safety, the dangerous and harmful factors, and puts forward the corresponding countermeasures and suggestions from these five aspects. In addition to the analysis of the security risk of the above operations, the paper analyzes the risk factors in the safety management, and clarifies the shortcomings of the safety management, which will lay an important foundation for the improvement of the level of safety management and the implementation of the system. This paper also studies two outstanding problems of coal railway special line, that is, level crossing and determination of maintenance cycle. Based on the above analysis of the factors affecting the safety of coal railway private lines, a safety evaluation index system matching the present safety situation of coal railway private lines in China is established, and the weight of each index is given by using fuzzy analytic hierarchy process (FAHP). The dynamic fuzzy theory is used to set up the safety evaluation model of railway private line, to calculate the fuzzy value of index at all levels, to evaluate the grade, to obtain the development trend of the index, and to form the dynamic evaluation result of railway private line. To provide reference and basis for private line safety management. Finally, the feasibility of the model is verified by evaluating the safety of the special line of Chitabai Railway.
