Research on the Rules of Overlying Rock Movement by Similar Material Simulation in Fully Mechanized Top Coal Caving Mining with High Cutting Height

Abstract:

In order to study overlying rock movement rules of fully mechanized top coal caving mining with high cutting height, taking 8100 working face of Tongxin mine as the engineering background, basing on the similarity theory and similarity simulation experiment, the paper analyzed overlburdens deformation, failure and movement laws after mining. Through research, results obtained first cave pace of immediate and basic roof, three zones characteristics and overburden displacement characteristic, which could provide a basis for coal mining under similar conditions, a reference for studying overburden movement rules of fully mechanized top coal caving mining with high cutting height and a guide for safe production.
