摘　　要：根据某开采煤矿各工作面的监测数据,建立煤矿井下瓦斯与煤尘的数学模型,运用MATLAB数学软件得到的相关数据,判断该煤矿为高瓦斯煤矿;再依据得到的数据建立线性规划模型,用LINGO软件计算得出该煤矿的不安全程度大值为14.07%,即该煤矿发生爆炸事故的可能性为14.07%;建立模型确定该矿井中总的通风量、各采煤工作面所需的通风量和局部通风机的额定风量。According to the monitoring data of each working face of a mining coal mine,the mathematical model of underground coal mine gas and coal dust is established and the relevant data obtained by MATLAB mathematical software is used to judge that the coal mine is a high-gas coal mine.And then based on the obtained data,a linear programming model is set up to calculate the large value of the degree of insecurity of this mine with LINGO software to obtain the large value of the degree of insecurity of this mine which is 14.07%.In other words,the probability of the occurrence of the explosion in this mine is 14.07%.Then the researcher builds a model to determine the total ventilation in the mine,the ventilation required by each coal working face and the rated airflow of local ventilation fan so as to achieve the purpose of safe production in the coal mine.
