乌达矿区煤自燃预测标志气体研究

为遴选预测煤自燃进程的标志气体,采集了乌达矿区6个具有代表性的煤样.在实验室开展煤升温氧化气体产物的测定实验,主要测试了煤样在升温氧化条件下各种气体组分的发生量.根据各种气体组分的发生量及最低检测温度,确定了乌达矿区煤自燃预测预报的标志气体,为该矿区煤自燃火灾的预测预报提供了实验依据,对矿区的安全生产具有较好的指导作用.

Study on sign gas for predicting coal spontaneous combustion in Wuda mine area

To select the sign gas for forecasting the course of coal spontaneous combustion, six representative coal samples are collected, and the measurement experiment of oxidation gas products in the process of temperature_rise, which are controlled by procedure in the laboratory, is carried out. The occurrence amount of oxidation gas products is primarily recorded. The sign gases can be confirmed according to the occurrence amount of gas components and the lowest critical temperatures, so the experiment data can be provided to forecast and predict the mine fires caused by coal spontaneous combustion. Most of all, this is a perfect guide to the safety production in the mine areas according to the sign gases.
