斜沟煤矿厚煤层综放开采对覆岩移动及地表沉陷规律研究

Oblique groove coal mining thick coal seam mining patterns of strata movement and surface subsidence

为了测定地表在采动影响下的变形规律,掌握我矿区可靠的地表岩移参数,晋兴公司委托山东中煤物探测量总公司对我矿21采区的23103工作面进行岩移观测。以地表实测数据为依据,分析研究该地质条件下,综放开采工艺对地表沉陷及变形特点和规律,并采用概率积分法求取岩移预计参数和岩移角值,为"三下"采煤及煤柱留设提供可靠基础资料和技术保障。

in order to determine the deformation law under the influence of the ground surface in mining, master I mine reliable surface rockmovement parameters, JinXing company entrusts ShanDong head office on 21 I mine mining area coal exploration surveying 23103 face ofrock movement observation. Analysis on the basis of the observed data of the earth＇s surface, the geological and mining conditions in fullymechanized mining surface subsidence deformation regularity and characteristics of the probability integral method to calculate the rockmovement parameters and rock displacement is expected value, for the ／＂three under／＂ mining and coal pillar design, provides reliable basicdata and technical support.
