| 摘 要： | 为了研究工作面突出区域预测问题，以车集煤矿2614工作面为基地，结合区域预测指标，在综合考虑该工作面的煤体结构、煤层瓦斯含量、瓦斯压力及瓦斯涌出量等参数后，将工作面突出区域预测指标确定为瓦斯含量。通过实验室模拟研究并结合现场实测参数确定该矿瓦斯含量临界值为9．0m^3／t，并以此为依据将工作面划分为突出危险区和非突出危险区。生产实践结果表明，按照上述指标体系和方法进行工作面突出区域预测是可行的。

| Abstract: | In order to study on the regional outburst prediction of the coal mining face,taking No.2614 coal mining face of Cheji Mine as an example,in combination with the regional predicted indexes,in comprehensive considerations on the coal mass structure of the coal mining face and the seam gas content,gas pressure and gas emission quantity as well as other gas parameters,the regional outburst predicted indexes of the coal mining face were determined as the gas content.With the indoor simulation study and in combination with the site measured parameters,the critical value of the mine gas content was determined as 9.0 m3/t and the coal mining face was divided into outburst danger zone and non-outburst danger zone.The production practice results showed that the regional outburst prediction of the coal mining face with the above index system and method would be feasible. |
