摘要
豫西一带含煤地层中的滑动构造相对发育。滑动构造引起煤层顶底板附近岩石力学性质发生变化,进而影响岩体的分带性。从研究嵩山井田滑动构造的分布范围、滑体的组成和滑动形态入手,采用岩石特征研究、构造形态分析和岩体质量指标(RQD)定量等研究方法,对影响二1煤层顶板的工程地质条件进行了分析,划分出三个不同工程地质性质的分带:岩体正常带、构造影响带和破碎带,并对各分带的岩体特征进行详细论述,为今后煤矿的安全开采提供了依据。
The sliding structure is comparatively well developed in western Henan. It causes alteration of rock mechanical property, thus impacts rock mass engineering geological zonality. Starting with research on the sliding structure distribution range, slide mass composition and sliding configuration in Songshan minefield analyzed Ⅱ1 coal roof engineering geological conditions through studies on rock property, structural form and rock quality designation （RQD）, and then three engineering geological belts divided, namely normal rock mass belt, structurally impacted belt and fracture belt. These results could provide with scientific basis for safe coal mining in the future.
