通过分析平顶山矿区己组煤的突出特征,掌握了煤层突出危险性与地质构造、构造软煤厚度、瓦斯赋存,特别是与日常生产中容易获取的各预测参数之间的关系,初步分析并确定了非突出煤层升级的预警指标及其临界值:构造软煤厚度为0.5 m,瓦斯含量为8.0 m3/t,瓦斯涌出量为2 m3/min,q值为3.5l/min,对于指导突出预测和防突工作具有重要意义。
Through the analysis of the outstanding features of self-assembled coal in Pingdingshan mining area, it has mastered the prominent danger and geological structure of coal seam, and constructed the relationship between soft coal thickness and gas occurrence, especially with the various predicted parameters easily obtained in daily production. The pre-warning index and its critical value for the non-salient coal seam upgrading are determined: the soft coal thickness is 0.5 m, the gas content is 8.0 m3 / t, the gas emission is 2 m3 / min and the q value is 3.5 l / min, It is of great significance to highlight the prediction and prevention efforts.
