摘要
Abstract
Aimed at effectively controlling the roof of goaf, this paper describes a field test of the partial filling of goal, based on controlling mechanism of goal filling, at the right fourth part of the third mine, ninth panel of Taoshan coal mine in Qitaihe by using the high water materials. The test consists of the reasonable selection and arrangement of filling pipes, and the mechanism analysis of the mechanics, structure and pressure of the filling. The result show that the filling, capable of actively binding roof, contributes to preventing the deformation of the old roof effectively and increasing the recovery ratio of coal. All the indexes of field test, up to the underground filling requirements, can offer reference for the filling of goal in other coal mines with similar geological conditions.关键词
