| 摘 要： | 围岩气异常涌出已成为严重威胁煤油气共生矿井安全高效开采的新的隐蔽致灾因素。以煤油气共生矿井围岩气储集层分布为基础，结合对围岩气控气要素的分析，提出了基于地质构造、岩性（砂岩透镜体和砂体上倾尖灭）、围岩气储集层分布和煤炭开采采动影响等多因素耦合下的煤油气共生矿井围岩气区域综合预测技术。采用该技术对黄陵二号煤矿2号煤层围岩气分布进行了区域综合预测，将矿井围岩气区划为Ⅰ级、Ⅱ级和Ⅲ级，并指出了矿井围岩气重点防范区域，减少围岩气防御面积近30%。

Prediction technology of surrounding rock gas zones by multiple factor coupling in coal mines with coal-oil-gas coexistence |
| |
| Abstract: | Unusual gas emission from surrounding rock has been a serious threat to work safety and efficient mining in coal mines with coal-oil-gas coexistence. Based on surrounding rock gas reservoir distribution, combining with the analysis of the factors controlling gas occurrence, this paper puts forward a multi-factor coupling technology of regional prediction of surrounding rock gas on the basis of geologic structure, lithology, gas reservoir, and mining influence. Using the technology, the distribution of surrounding rock gas of coal seam 2 in Huangling coalmine No.2 was predicted, the zonation of surrounding rock gas was completed. The key areas to prevent surrounding rock gas were pointed out, the defense area of surrounding rock gas was reduced by nearly 30%. |
