【摘要】：随着我国煤矿企业逐步进入深部化开采阶段,煤炭生产过程中各类事故灾害发生的可能性也在增大,井下避险逃生线路长度也随着开采深度的增而增大,为确保井下作业人员在事故灾害发生后能够安全脱险,煤矿井下紧急避险系统的建立和完善至关重要。通过分析国内外紧急避险的发展和应用现状,发现我国煤矿紧急避险系统的建设还存在明显的不足。本文首先对紧急避险系统的组成部分进行了简单介绍;在此基础上,以唐口煤矿430采区为例进行紧急避险系统的设计,对采区永久避难硐室的选址位置、基本结构及功能设计进行了详细的设计,针对该矿的火灾和煤尘爆炸等重大灾害,根据对爆炸冲击波超压计算以及人员逃生时间估算,确定了临时避难硐室的合理选址位置;基于未确知测度理论,建立煤矿井下紧急避险系统评价模型对设计的紧急避险系统进行可靠性评价,经计算评价结果为“较可靠性”;对紧急避险系统中的紧急避灾路线进行深一步研究,通过对比分析几种最短路径算法,选择Dijkstra算法作为基本算法,实现了煤矿紧急避灾路线的优选;最后,利用 MicrosoFt Visual Basic 6.0、ArcGis10.2、AutoCAD2008、SQL Server2008等工具完成煤矿井下紧急避险信息系统的开发设计,该系统以避灾路线优选和可视化为核心,包含了系统管理、预案管理、避灾路径、培训教育、组合查询、系统帮助等六大模块。煤矿井下紧急避险信息系统既可用于实施科学、有效的紧急避险管理,也可用于开展科学、直观的职工培训教育,为矿山事故的紧急避险和应急救援工作提供可视化信息,具有较强的实用性。
[Abstract]:As China's coal mining enterprises step by step into the stage of deep mining, the possibility of all kinds of accidents and disasters in the coal production process is also increasing, and the length of underground escape line increases with the increase of mining depth. In order to ensure the safe escape of underground operators after the accident disaster, it is very important to establish and perfect the emergency risk avoidance system in coal mine. Based on the analysis of the development and application of the emergency risk avoidance system at home and abroad, it is found that there are still obvious deficiencies in the construction of the coal mine emergency shelter system in China. In this paper, the components of the emergency shelter system are introduced briefly, and on the basis of this, the design of the emergency shelter system in the mining area 430 of Tangkou Coal Mine is taken as an example, and the location of the permanent shelter chamber in the mining area is selected. The basic structure and function are designed in detail. According to the overpressure calculation of explosion shock wave and the estimation of personnel escape time, the reasonable location of temporary shelter chamber is determined according to the fire and coal dust explosion and other major disasters in the mine. Based on the theory of unascertained measure, the evaluation model of underground emergency risk avoidance system is established to evaluate the reliability of the designed system. The result of calculation and evaluation is "more reliable". By comparing and analyzing several shortest path algorithms, Dijkstra algorithm is selected as the basic algorithm to realize the optimal selection of the emergency disaster avoidance route in coal mine. The development and design of underground emergency risk avoidance information system in coal mine is completed by means of MicrosoFt Visual basic 6.0 / ArcGis10.2 / AutoCAD2008 / SQL Server 2008 etc. The system takes disaster avoidance route selection and visualization as the core, and includes system management, plan management, disaster avoidance path, training and education, combination query, etc. System help and other six modules. The underground emergency risk avoidance information system can be used not only to implement scientific and effective emergency risk management, but also to carry out scientific and intuitive training and education of workers and staff, and to provide visual information for emergency risk avoidance and emergency rescue work of mine accidents. It has strong practicability.
