针对煤的钻屑温度和煤体温度对煤和瓦斯突出危险区域的敏感性,定义了预测掘进工作面突出危险性两个温度敏感指标;论述了两个温度指标作为预测突出危险性指标的依据和确定两个温度指标的方法。在此基础上,探讨了两温度指标预测掘进工作面突出危险性的实施方法及步骤;同时,根据现场的考查和确定敏感指标的要求,确定了被考查区域两个温度敏感指标的临界值
According to the sensitivity of cuttings temperature and coal body temperature to coal and gas outburst danger area, two temperature-sensitive indexes for predicting the outburst danger of heading face are defined. Two temperature indexes are discussed as the basis for predicting the prominent risk index And to determine the two temperature methods. On this basis, the methods and steps for predicting the prominent danger of roadway heading by two temperature indexes are discussed. At the same time, the critical values of two temperature-sensitive indexes in the investigated area are determined according to the requirements of on-site inspection and determination of sensitive indexes
