复合型顶板煤层组合滑移支架适用性研究
Applicability of Combined Sliding Support in Complex Roof
摘要
Abstract
In order to solve the problem of coal resources safety and efficient recovery in irregular block segments and corner fragments under the complex roof support in Didaoshenghe Mine of Jixi Mining Group,this paper introduces the application of combined sliding support in this mine.Combining theoretical calculation and field data acquisition and analysis,the stability of the combined sliding support in the coal seam is studied.Results show that the front and rear columns of the combined sliding support are subjected to different main loads under the different roof conditions,and the working resistance of the support is within its rated working resistance range,and the adaptability of the vertical section is common.The combined sliding support is generally used in the mine production geology,and can meet the demand of mine production and obtain some technical and economic benefits.关键词
