煤与瓦斯突出是一种极其复杂的动力现象。但就其影响因素而言,主要有地应力、瓦斯和煤的物理力学性质。工作面附近煤体温度与前两个因素的关系是:当煤体应力增加,其温度升高;在卸压或排放瓦斯时、温度则降低。苏联学者马耶夫斯基等的研究表明,瓦斯解吸时煤体温度的降低,大大超过机械加载时温度的升高。因此,许多国家都开展过应用煤体温度变化预报突出危险的研究。波兰早在 Coal and gas outburst is an extremely complex phenomenon of power. However, in terms of its influencing factors, there are mainly geostress, physical and mechanical properties of gas and coal. The relationship between the temperature of the coal body near the working face and the first two factors is that when the stress of the coal body increases, the temperature of the coal body rises; when the pressure is released or discharged, the temperature decreases. Research by the Soviet scholar Maievski et al shows that the temperature of the coal decreases as the gas is desorbed, much more than the temperature rise during mechanical loading. Therefore, many countries have carried out research on the prominent dangers of using coal body temperature forecasting. Poland is early
