本文件给出了煤矿采用钻孔指标法开展突出煤层煤巷掘进工作面煤与瓦斯突出危险性预测的总体要求、 适用情形、 方法与依据、 工艺与流程、 数据分析及资料管理等内容,重点体现了预测工作应实施全过程闭环管理的要求, 提出了预测钻孔施工宜采取视频监控. 摘 要:煤与瓦斯突出危险性预测关系到瓦斯治理措施的有效实施。为提高煤层隐伏小断层附近瓦斯治理的效果, 结合煤与瓦斯突出的主要影响因素,提出了小断层附近煤与瓦斯突出危险的动态分析方法, 包括瓦斯地质条件勘查、 瓦斯地质数值建模、采动应力场演化. 按本细则第十三条要求进行鉴定,结果为非突出煤层但具有下列情况之一的,应当在采掘作业时考察煤层的突出危险性,包括观察突出预兆、分析瓦斯涌出变化情况等,并在井巷揭煤、煤巷掘进及采煤工作面分别采用本细则第八十七条、第八十九条、第九十三条的方法.
该标准规定了突出煤层区域预测的组织实施流程，明确了开拓前后区域预测方法（包括瓦斯参数结合地质分析法、多指标综合预测法等）及预测报告编写要求。 本文件规定了突出煤层区域预测的一般要求、预测依据、预测方法、预测结果判定、区域预测图填绘、区域预测报告编制。 摘要: 为了确定突出煤层工作面突出危险性预测敏感指标，确保工作面突出危险性的精准预测,以四季春煤矿6号煤层为例，通过总结分析邻近区域及矿井6号煤层煤与瓦斯突出特征，构建了6号煤层工作面突出危险性预测指标敏感性分析标准。
第三十七条 对已确切掌握煤层突出危险区域的分布规律，并有可靠的预测资料的，区域预测工作可由矿技术负责人组织实施；否则，应当委托有煤与瓦斯突出危险性鉴定资质的单位进行区域预测。
判定各煤层煤巷掘进工作面突出危险性的临界值应当根据试验考察确定，在确定前可暂按以下指标进行预测：当所有钻孔的R值小于6且未发现其他异常情况时，该工作面可预测为无突出危险工作面；否则，判定为突出危险工作面。 区域预测（长期预测），其任务是确定矿井、煤层和 煤层区域的突出危险性。 区域预测应在地质勘探、新 井建设、新水平和新采区开拓或准备时进行。
