摘要
在分析试验区水力掏槽措施参数的基础上,从槽硐径向半径与地应力关系、槽硐径向半径与瓦斯内力关系、掏槽深度与应力变化关系、槽硐轴向深度与瓦斯内力关系等角度,深入分析其在突出厚煤层中快速掘进的防突机理,并通过数据统计验证了水力掏槽快速掘进防突技术在突出厚煤层应用的优越性,为突出厚煤层矿区应用该措施提供理论基础和实践经验。
On the basis of parameter analysis of hydraulic cutting ol experimental area, the outburst prevenUon mecnamsm oi rapla excavation m outburst thick coal seam is deeply analyzed from the relationship between radial radius of hole and ground stress, between radial radius of hole and intrinsic gas energy, between cutting depth of hole and stress change, between axial depth of hole and intrinsic gas energy, etc. The superiority of hydraulic cutting technique apply to outburst thick coal seam is verified by data statistic, which provided the theoretical foundation and experience for the measure apply to outburst thick coal seam mining area.
