Abstract

The invention relates to the technical field of coal mining, in particular to a coal mining roadway supporting device and a supporting method. Wherein the support device comprises a filling mold, the filling mold is vertically arranged on the bottom plate of the roadway to be supported, and the upper end of the filling mold is open; the filling body is filled in the filling mold to form a support column, and the support column The upper end is connected with the roof of the roadway to be supported. It also relates to a support method for a coal mining roadway. First, a filling mold is set between the top plate and the bottom plate of the area to be supported in the roadway; then, filling bodies are filled into the filling mold to form a support column; The support column is fixedly connected with the roof, and the support device made by this support method can replace the stacked support as the external support of the pre-excavation withdrawal channel, and the structure is relatively simple, and the filling body is filled into the filling mold The supporting column that supports the coal mining roadway can be obtained, which greatly saves the steps of supporting and reduces the cost of supporting.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a coal mining roadway supporting device and a supporting method. Background technique [0002] In the field of coal mining, in order to facilitate the relocation of the coal mining face, pre-excavation withdrawal passages are often set up. At the end of coal mining, external supports must be installed in the pre-excavation withdrawal passages to ensure the safety of the pre-excavation withdrawal passages. Therefore, the support of the pre-excavation withdrawal channel has become an important preparation work for the withdrawal of the fully-mechanized mining face, and it is also a key factor restricting the increase of the unit yield level of the fully-mechanized mining face. [0003] The support of the pre-excavation withdrawal channel mainly includes two parts: internal support and external support. The internal support is a support system composed of anchor rods and anchor ...
