【摘要】：榆神府矿区是我国亿吨级产量的煤炭基地之一,然而随着矿区开采程度的增加,顶板水灾害问题已逐渐成为影响矿井安全生产的主要危害因素。因此,研究一套能够及时准确的对顶板水灾害进行预警的监测系统,对矿井安全生产具有重要的工程应用意义。本文以系统科学理论和方法为理论基础,通过分析浅埋煤层顶板水灾害预警系统的内涵以及系统构成元素,建立了浅埋煤层顶板水灾害预警系统的逻辑分析框架及系统结构分析模型。依据榆神府矿区水文地质条件分析了影响矿井顶板水灾害事故发生因素。结合韩家湾煤矿实际情况,以突水水源、导水通道、隔水能力、预防工作为一级指标,建立影响矿井水害致灾因素的层次模型。运用层次分析法中权重向量的四种计算方法结合专家意见法对影响矿井水灾害因素进行了综合权重评价,得出对韩家湾煤矿产生水害隐患最大的因素是地表水和松散含水层水。确定了以水位、水温、水压、应力为主的韩家湾煤矿顶板水灾害监测预警系统的具体监测指标。通过分析浅埋煤层顶板水灾害预警系统的设计目标、系统特点、系统组成及功能需求,运用VISUAL C++程序设计语言结合MYSQL数据库开发了韩家湾煤矿顶板水灾害预警系统软件。该系统在韩家湾煤矿水库下的1401工作面进行了成功预警。
[Abstract]:Yushenfu mining area is one of the coal bases for the production of 100 million tons of coal in China. However, with the increase of mining degree, the problem of roof water disaster has gradually become the main hazard factor affecting the safety of mine production. Therefore, the study of a monitoring system which can timely and accurately warn roof water disaster has important engineering application significance for mine safety production. Based on the theory and method of system science, this paper analyzes the connotation and system elements of the early warning system for roof water disaster in shallow coal seam. The logical analysis framework and system structure analysis model of the early warning system for roof water disaster in shallow coal seam are established. According to the hydrogeological conditions of Yushenfu mining area, the influencing factors of mine roof water disaster are analyzed. Combined with the actual situation of Hanjiawan Coal Mine, a hierarchical model of influencing factors of mine water disaster was established with water inrush water source, water diversion channel, water isolation capacity and prevention work as the first class index. By using four calculation methods of weight vector in Analytic hierarchy process (AHP) combined with expert opinion method, the comprehensive weight evaluation of factors affecting mine water disaster is carried out. It is concluded that surface water and loose aquifer water are the biggest factors of potential water hazard in Hanjiawan Coal Mine. The monitoring index of roof water disaster monitoring and warning system in Hanjiawan coal mine is determined, which is based on water level, water temperature, water pressure and stress. Based on the analysis of the design objectives, system characteristics, system composition and functional requirements of the early warning system for roof water disaster in shallow coal seam, the software of the roof water disaster early warning system of Hanjiawan Coal Mine is developed by using VISUAL C programming language and MYSQL database. This system has carried on the successful early warning in the 1401 working face under the Hanjiawan coal mine reservoir.
