【摘要】：随着煤矿安全受到社会各界的广泛关注,矿井事故的发生必将严重影响着企业的正常生产和可持续化发展。现阶段我国很多煤矿都面临着矿井突水的威胁。一旦煤矿巷道发生突水事故时,不仅会使煤矿停工停产造成重大经济损失,甚至会严重威胁井下工作人员的生命安全。制定紧急避灾路线是煤矿应急救援体制中最重要的内容之一,是当水灾发生时井下工作人员迅速及时撤至安全位置的关键因素。井下突水最优避灾线路的研究成为避灾救援的一个重要课题。本文针对以上问题,以山西省某煤矿水文地质相关资料为基础,综合运用计算机Visual C#编程、数据库、GIS等先进技术,基于矿井水文地理信息系统二次开发的,对矿井突水时期的最优避灾路径进行研究。具体的研究内容如下:(1)阐述了煤矿突水的因素以及征兆,叙述了最优路径和K则最优路径的概念,然后介绍了求取最优路径的几种方法,并进行比较。(2)针对矿井水害避灾过程中,逃生路径受巷道实际当量长度影响的特点,本文在充分考虑巷道的可通行性及巷道的各影响因素,引入时间影响因子,确定其当量长度。在改进的Yen算法思想的基础之上,建立K则最优避灾路径的数学模型。(3)在综合分析系统需求和完善系统设计的基础上,以ArcGIS Engine和Visual Studio 2010为开发平台,以山西省某煤矿水文地质资料为依据,利用C#程序设计语言进行开发,获得了该煤矿巷道网络的K则最优避灾路径。
[Abstract]:With the coal mine safety has been widely concerned by all walks of life. The occurrence of mine accidents will seriously affect the normal production and sustainable development of enterprises. At this stage, many coal mines in China are facing the threat of mine water inrush. Not only will the coal mine shutdown cause great economic losses, but also will seriously threaten the safety of underground workers. The formulation of emergency route is one of the most important contents in the coal mine emergency rescue system. It is the key factor for the downhole workers to withdraw to the safe position in time when the flood occurs. The research of the optimal route of underground water inrush becomes an important subject of disaster avoidance and rescue. This paper aims at the above problems. Based on the hydrogeology related data of a coal mine in Shanxi province, the secondary development of mine hydrographic geographic information system is carried out based on the advanced technology of computer Visual C # programming and database GIS. The specific research contents are as follows: 1) the factors and symptoms of coal mine water inrush are expounded, and the concepts of optimal path and K optimal path are described. Then several methods to obtain the optimal path are introduced and compared. 2) aiming at the characteristics that the escape path is affected by the actual equivalent length of roadway in the process of mine water disaster avoidance. In this paper, considering the passability of roadway and the influence factors of roadway, introducing the time influence factor to determine the equivalent length, on the basis of the improved Yen algorithm. The mathematical model of K optimal path of disaster avoidance is established. (3) on the basis of comprehensive analysis of system requirements and improvement of system design. Based on the development platform of ArcGIS Engine and Visual Studio 2010, and based on the hydrogeological data of a coal mine in Shanxi Province. By using C # programming language, the K optimal disaster avoidance path of the coal mine roadway network is obtained.
