Study on the Movement of Overlying Strata in Shallow Depth of Burial and Thin Bedrock Under Multi-factor Synergism
摘要
Abstract
Based on special occurrence characteristic of shallow depth of burial and thin bedrock coal seam,through the orthogonal test designed by the FLAC3D numerical simulations systematically analyzes the influence of multi-factor ( bedrock thickness, loose bed thickness, mining height and advancing speed ) synergism on the movement behavior of overlying strata in shallow depth of burial and thin bedrock;The primary and secondary factors are obtained, which influences shallow thin bedrock face roof strata moving. Results show that from the different index of strata movement, the importance of the factors that affect strata movement is not the same. From the perspective of initial pressure, bedrock thickness is the main factors affecting;From the respect of periodic weighting, loose bed thickness is the main factors affecting; while from the aspect of the surface displacement, mining height is the main factors affecting; Taken together, the influence factors from main to secondary are bedrock thickness, loose bed thickness, mining height and advancing speed.关键词
