【摘要】 瓦斯事故一直威胁着煤矿的安全生产,近几年来矿难更是频频发生,造成重大人员伤亡和财物损失。寺河煤矿属高瓦斯煤层,瓦斯危害相当严重。长期以来,煤矿事故管理总是强调事后处理,由于受管理人员的知识、经验和责任心的限制,很难适应矿井瓦斯灾害的复杂多变条件。根据国家对煤矿安全生产的要求,所有矿井都必须配备安全监测系统。但现有安全监测系统还不能满足煤矿企业对安全生产的要求,功能有待完善。如采集数据的实时统计和瓦斯涌出量的预测等方面仍有欠缺。本文首先对现有煤矿安全监测系统进行了详细的研究,结合煤矿企业安全管理方面的具体需求,确定了煤矿安全监测系统所需要完善的功能。并且对本系统进行了详细的分析与设计。利用“紫金桥”组态软件对现有煤矿安全监测系统的监测数据进行实时的读取及存储,以实时曲线的方式来显示,并加以实时的统计、分析功能;当监测的数据超过设定值时启动报警功能,以声、光方式直接反映给使用者,同时以手机短消息的形式将信息发送给管理人员;进而基于经典BP网络的基本原理,利用瓦斯管理系统中自动计算的相应数据,建立瓦斯涌出量预测模型,对矿井瓦斯涌出量进行预测。提高了煤矿企业安全生产管理水平,不需要重新布置传感器及线缆,节省企业开支,具有实用的意义。更多还原

【Abstract】 Coal mine gas accident has been threatening the safety of the production, mining accidents in recent years, more frequent, causing heavy casualties and property loss. Sihe Coal Mine is a high-gas coal seam gas hazard is very serious. For a long time, coal mine accident management has always stressed that post-processing, due to management knowledge, experience and responsibility limitations, it is difficult to adapt to the complex conditions of coal mine gas disaster.According to the requirements of safe production in coal mines, all mines must be equipped with security monitoring system. However, the existing safety monitoring system also can not meet the coal mine production safety requirements business, functions to be improved. If the data and prediction of gas emission statistics in real-time security information is still lacking.First, this article of the existing coal mine safety monitoring system carried out a detailed study of the safety management of coal mining enterprises with the specific needs of identified coal mine safety monitoring system needed to improve the function. And to conduct a detailed analysis and design for this system. Use of "Zijin Bridge" configuration software on the existing coal mine safety monitoring system for real-time monitoring data read and stored in real-time mode to display the curve, and make real-time statistical analysis functions; When the monitored data exceeds a set value, start the alarm functions to sound, light directly reflected to the user, while mobile phone short message in the form of information to managers; and then based on the classical BP network, the basic principle of the use of gas management the system automatically calculate the corresponding data, to establish the amount of gas emission prediction model, to predict the amount of coal mine gas emission. Improve coal mine safety production management level of enterprises do not need to re-arrangement of sensors and cables, to save corporate expenses, has practical significance.更多还原
