中文摘要：

通过对梁北煤矿21030工作面瓦斯活动资料的收集、整理及现场瓦斯参数的测定,利用朗格缪尔方程推算出工作面中瓦斯压力。在综合考虑煤体结构及煤层瓦斯参数基础上,根据煤与瓦斯突出预测敏感指标及临界值,对工作面煤与瓦斯突出危险性进行了预测;预测结果表明,21030工作面具有煤与瓦斯突出危险。

英文摘要：

With the collection and processing of the gas activities information and the measurement of the site gas parameters in No.21030 coal mining face of Liangbei Mine,the Langmuir equation was applied to calculate the gas pressure in the coal mining face.Base on the consideration of the seam structure and the seam gas parameters,according to the sensitive index and the critical value of the coal and gas outburst prediction,a prediction on the coal and gas outburst danger was conducted.The prediction results showed that No.21030 coal mining face would have a coal and gas outburst danger in potential.
