| 摘 要： | Based on the deformation characteristics of the roadways driven along goaf in fully mechanized top-coal caving faces, the author considers that it is the key to ensure the stabili-ty of surrounding rocks of roadway driven along goaf to control the deformation during the pe-riod affected by mining. Considering the characteristics of the roadway layout in fully mecha-nized top-coal caving faces, a technical scheme of destressing is put forward and the de-stressing effect is analyzed by using the software of Universal Distinct Element Code 3.0( UDEC 3.0).

| Abstract: | Based on the deformation characteristics of the roadways driven along goaf in fully mechanized top coal caving faces, the author considers that it is the key to ensure the stability of surrounding rocks of roadway driven along goaf to control the deformation during the period affected by mining. Considering the characteristics of the roadway layout in fully mechanized top coal caving faces, a technical scheme of destressing is put forward and the destressing effect is analyzed by using the software of Universal Distinct Element Code 3 0(UDEC 3 0). |
