摘要
为了揭示厚松散层、岩层与地表移动的内在机理和规律,丰富和发展开采沉陷理论,应用数理统计原理整理和分析了大量的实测资料,采用概率积分法和最小二乘原理进行拟合求参,分析总结了相应的角量参数、概率积分法预计参数规律以及中采深厚松散层的特点.利用多元回归分析,得出了同一矿区虽然采厚变化不大,但松散层厚度对边界角、移动角的影响较为显著,且边界角和移动角相差很大,甚至可达20,°最后总结了目前控制和减轻地表沉陷的主要技术途径.这对研究开滦矿区厚松散层条件下地表岩移规律和开采沉陷问题具有重要指导意义和应用价值.
First,in order to reveal the inherent mechanism and patterns of the thick unconsolidated layeas,the rocks and ground movements,and enrich and develop the theory of mining subsidence,it reorganizes and analyzes the massive actual materials with the mathematical statistic principle,carries on the fitting by the probability integration and smallest two rides principle,analyzes and summarizes the corresponding angular parametes,the probability integration estimate parameter and the characteristic of the deep thick unconsolidated layers.Then,with multiple regression analysis,it obtained that though thick change of mining thickness is little in the identical mining area,the thick unconsolidated layer＇s influence is more remarkable for the boundary angle and the motion angle,and the boundary angle and the motion angle vary widely,even achieves 20°.Finally,it summarizes the present major technique ways that control and reduce the surface subsidence.It has the important directive significance and using value for studying the rule of surface rock movement and the mining subsidence problems with thick unconsolidated layer in Kailuan mining area.
