煤层自燃预警系统设计研究

Research and Design of Coal Bed Spontaneous Combustion Warning System

煤层自燃灾害历来是影响煤矿安全生产的主要灾害之一。通过分析我国煤层自燃的现状,建立了煤层自燃灾害预警指标体系,包括标志气体信息和温度信息,并指出了标志气体要根据不同矿井煤层煤质的煤样实验燃烧结果来确定。介绍了构建本系统涉及到的关键技术:3S技术、数据库技术(数据挖掘和数据融合)、计算机辅助决策系统(模糊数学综合评价和专家系统)等。构建了煤层自燃灾害预警系统,为系统的开发设计提供了整体框架和基本思路。对煤矿的安全生产具有十分重要的意义。

Tbe coal bed spontaneous combustion disaster is always one of coal mine safety production major casualties. This paper analyzed our country coal bed spontaneous combustion the present situation and established the warning indicator system of the coal bed spontaneous combustion disaster, including symbol gas information and temperature information, and pointed out that symbol gases are determined according to the coal sample experiment combustion result oftbe different mine coal bed＇s anthrax. And the key technologies of the system introduced, which involved 3S technology, database technology （data mining and data fusion）, computer auxiliary decision system （fuzzy mathematics quality synthetic evaluation and expert system） and so on. The coal bed spontaneous combustion disaster early warning system was constructed, which has provided the overall frame and the basic mentality for system＇s development and has the very vital significance to the coal mine safety in production.
