摘要
为提升煤与瓦斯突出预测和防治的准确性、可靠性和效率,首先,基于煤层瓦斯赋存规律、吸附解吸特征及瓦斯运移规律相关理论构建掘进工作面瓦斯参数反演模型;其次,将瓦斯反演模型内嵌到煤与瓦斯突出实时监测预警系统软件中,对石屏一矿C19上煤层13019上机巷掘进工作面的瓦斯含量和瓦斯压力进行反演预测;最后,采用DGC瓦斯含量直接测定法实测现场数据对模型反演结果进行对比验证。反算数值与实测数值对比表明,煤体瓦斯含量和压力反演计算结果准确可靠。
In order to improve the accuracy,reliability and efficiency of coal and gas outburst prediction and prevention,firstly,based on the relevant theories of coal seam gas occurrence law,adsorption and desorption characteristics and gas migration law,the inversion model of gas parameters in heading face is constructed.Then,the gas inversion model is embedded into the real-time monitoring and early warning system software of coal and gas outburst to invert and predict the gas content and gas pressure of the heading face of 13019 upper machine roadway in coal seam C19 of Shiping No.1 Mine.Finally,the field data of DGC gas content direct measurement method are used to compare and verify the inversion results of the model.The comparison between the inverse calculation value and the measured value shows that the inversion calculation results of coal gas content and pressure are accurate and reliable.
