【摘要】:我国是世界矿产资源的开采大国,开采历史悠久,随着社会的进步和时间的推移,金属非金属无论在产量还是消耗量上在我国都占据着重要的地位。然而由于对金属非金属矿的需求量日益增大,开采规模日趋扩大,开采深度逐渐加深,再加上安全紧急避险系统不健全等因素,使得金属非金属地下矿山事故频频发生,人民的生命安全受到了严重的威胁,这对我国的社会稳定和经济发展都有很大的影响。因此对金属非金属地下矿山紧急避险系统设置进行优化研究势在必行。 本论文主要研究了我国金属非金属地下矿山紧急避险系统的设置和优化,以我国云南大红山铁矿的紧急避险系统设置为例,分析并优化其紧急避险系统,尤其是对避难硐室的设置进行了重点研究,目的是为了使得其避难硐室与其他紧急避险系统的组成部分有效配合,最终建立和优化一套从安全心理→紧急避险逃生路线→避难硐室的自救和互救→成功救援的紧急避险系统,最大的发挥紧急避险系统中各个组成部分的功能,达到对紧急避险的研究,以期提高我国金属非金属地下矿山的本质安全保障能力。本文主要从三方面进行研究:第一,主要加强该矿山的安全知识培训。从安全心理学出发,受过安全心理培训的地下矿工在井下作业时会对危险有一定的敏感度,当灾害事故发生后,矿下的人员可以依靠自己的能力和大家的力量,在良好的安全心理作用下,积极采取避灾自救措施,控制和缩小事故范围及其危害程度,把损失降低到最低限度。第二,主要研究建立井下合理的避灾路线。当灾害事故发生时,一条合理的正确的避灾路线可以使井下矿工安全、迅速的撤离危险区;或者地面救援队可以沿着避灾路线及时进行井下救援。第三,优化研究大红山铁矿永久避难硐室的位置及设计,当灾害事故发生时,井下矿工不能按避灾路线及时升井时,可以进入避难硐室安全的等待救援。第四,通过使用三维数值模拟软件FLAC3D对避灾路线中巷道以及永久避难硐室进行建模分析,确认了避灾路线以及避难硐室的可行性,为大红山铁矿避险系统的建设实施提供了依据。 本论文提出的优化方案对云南大红山铁矿井底避难系统的建设具有一定的参考价值,以期进一步加强我国金属非金属地下矿山本质安全的保障能力。
[Abstract]:China is a large mining country of mineral resources in the world. With the progress of society and the passage of time, non-metallic metals play an important role in the production and consumption of mineral resources in China. However, due to the increasing demand for metallic non-metallic mines, the increasing scale of mining, the deepening of mining depth, and the unsound safety and emergency risk avoidance system, accidents in metallic non-metallic underground mines occur frequently. The safety of people's lives is seriously threatened, which has a great impact on the social stability and economic development of our country. Therefore, it is imperative to optimize the installation of emergency risk avoidance system in metallic non-metallic underground mines. This paper mainly studies the establishment and optimization of the emergency safe havens system in the metal nonmetallic underground mines in China. Taking the emergency risk avoidance system of Yunnan Dahongshan Iron Mine as an example, this paper analyzes and optimizes the emergency hedge system. In particular, the establishment of the asylum chamber is studied in order to make it cooperate effectively with the components of other emergency risk aversion system. Finally, to establish and optimize a set of emergency shelter systems for self-rescue and successful rescue of each other from the safe psychological escape route and emergency escape route, so as to maximize the function of each component of the emergency shelter system. The purpose of this paper is to improve the essential safety guarantee ability of metal non-metallic underground mines in China. This article mainly carries on the research from three aspects: first, mainly strengthens the mine safety knowledge training. From the perspective of safety psychology, underground miners trained in safety psychology will have a certain degree of sensitivity to danger when they work underground. When a disaster occurs, the personnel under the mine can rely on their own ability and everyone's strength. Under the action of good safety psychology, we should take active measures to avoid disasters and save ourselves, control and reduce the range of accidents and their harm degree, and reduce the losses to the minimum. Second, the main research is to establish a reasonable downhole disaster avoidance route. When a disaster occurs, a reasonable and correct route of avoiding disasters can make the underground miners safely and quickly withdraw from the dangerous area, or the surface rescue team can carry out the underground rescue in time along the route of disaster avoidance. Third, optimize the location and design of the permanent shelter chamber in Dahongshan Iron Mine. When the disaster accident occurs, the underground miners can enter the refuge chamber safely and wait for rescue if they can not get up in time according to the disaster avoidance route. Fourthly, through modeling and analysis of roadway and permanent shelter chamber in disaster avoidance route by using 3D numerical simulation software FLAC3D, the feasibility of disaster avoidance route and shelter chamber is confirmed. It provides the basis for the construction and implementation of the risk-averse system in Dahongshan Iron Mine. The optimization scheme proposed in this paper has a certain reference value for the construction of bottom-hole asylum system of Yunnan Dahongshan Iron Mine in order to further strengthen the essential safety of metal non-metallic underground mines in China.
