| 摘 要： | 通过测定煤壁的瓦斯涌出强度和落煤的瓦斯解吸强度,建立煤壁和落煤的瓦斯涌出强度经验公式和瓦斯涌出量预测公式,从而建立综掘巷道的瓦斯涌出量预测模型。通过测定综掘巷道瓦斯涌出,对建立的计算模型进行验证。结果表明,煤壁和落煤的瓦斯涌出强度随时间的变化符合指数或双曲线关系,由该关系建立起的2种预测模型相互结合应用,能够很好地表达综掘巷道的瓦斯涌出规律。

| Abstract: | Through determining gas emission intensity data of the coal wall and caved coal,the experience formulas are obtained,then the gas emission mathematical models of a fully mechanized diving roadway are established by evaluating integrals with experience formulas.In order to certify the correct of prediction formulas,the gas emission quantity of a driving roadway named 11301 is measured.The results show the gas emission intensity variation of coal wall and caved coal with time could meet the double curve relationship or exponential function,the two prediction mathematical models based on the experience formulas can express the gas emission quantity variation of a fully mechanized driving roadway with time. |
