On the premise of not moving buildings, using the solid waste such as coal gangue to fill stoping under the buildings, can not only produced dull coal pillar resources, but can also handle a large number of coal gangue, alleviating the pressure of mine auxiliary lift, saving transportation costs, reducing solid waste emissions, and protecting the ecological environment of the surrounding residents, which is of great significance to the construction of harmonious mining area.
