Abstract EN
This paper deals with the theoretical aspects combined with stress analysis over the floor strata of coal seam and the calculation model for the stress on the coal floor.
Basically, this research presents the relevant results obtained for the rock burst prevention in the floor of roadway driven along next goaf in the exploitation of thick coal seam with large obliquity in deep well and rock burst tendency.
The control mechanism of rock burst in the roadway driven along next goaf is revealed in the present work.
That is, the danger of rock burst can be removed by changing the stress environment for the energy accumulation of the floor and by reducing the impact on the roadway floor from the strong dynamic pressure.
This result can be profitable being used at the design stage of appropriate position of roadway undergoing rock burst tendency in similar conditions.
Based on the analysis regarding the control mechanism, this paper presents a novel approach to the prevention of rock burst in roadway floor under the above conditions.
That is, the return airway is placed within the goaf of the upper working face that can prevent the rock burst effectively.
And in this way, mining without coal pillar in the thick coal seam with large obliquity and large burial depth (over a thousand meters) is realized.
Practice also proves that the rock burst in the floor of roadway driven along next goaf is controlled and solved.
