Comprehensive correlation technology of coal and rock layers in mines for intelligent mining

  • 摘要: 煤岩层对比工作贯穿于整个煤炭地质勘查与矿井生产阶段的全过程,针对近距离、多煤层且构造复杂的矿井生产阶段煤岩层对比困难的问题,以贵州盘县煤田火烧铺煤矿为研究对象,通过对地质勘查资料的分析,结合地面瓦斯勘查钻孔、井下地质调查、瓦斯参数测试工程从地质勘查阶段已经建立的煤岩层对比标志层中提取适应于矿井生产阶段的标志层;结合矿井生产过程中井筒、巷道、工作面及其两巷道、切眼等井巷工程生产揭露资料的宏/微观煤岩、煤质化验、煤层顶底板岩石力学、煤层的光学特征等资料,提炼矿井生产过程中基于开采技术条件的煤岩层对比的标志;综合地质勘查与矿井生产阶段重新构建矿井生产阶段煤岩层综合对比标准体系。研究表明:地质勘查阶段构建的煤岩层对比标志层在矿井生产阶段岩性组合、地球物理测井曲线,高位标志性岩层以及古生物化石层基本上失去了指导意义,而煤层结构、伪顶或低位直接顶板古生物化石层、岩性标志层仍具有指导意义,可以指导实践生产;矿井生产阶段大量的地层倾角数据、宏/微观煤岩组分特征、煤层夹矸岩性,尤其是可见光、热红外等光学特征,煤层瓦斯含量、压力参数,煤层顶底板岩石力学参数等是煤岩层对比的良好标志层;构建的煤岩层综合对比技术体系可以有效地指导煤矿巷道高效掘进、工作面快速回采并识别断层发育特征。研究成果不仅可以指导煤矿井下生产工作而且可以为构造复杂区的煤矿井下工作面智能化开采提供基础地质资料,为煤矿安全、高效、智能化开采提供地质保障技术。
