RESEARCH ON THE FULL MECHANIZED TOP COAL CAVING DESIGN AND COMPREHENSIVE MEASURES OF PREVENTING ROOK BURST FOR THICK SEAMS IN LARGE EMBEDDED DEPTH
Based on the series characteristics in the main coal seams, such as large embedded depth, high geo-stress, compound roof, complex structure, an modem and high-tech working face was designed for the first coal mine of Juye coalfield in East China. Advanced theories and techniques were adopted on support and full mechanized top coal caving method was used. Measures of preventing rock burst were put forward through numerical simulations and on-site observations. The results showed that the anchor and truss structure with high original strength and high initial stress had expectant effect on face tunnels support and top coal caving produced smoothly. The serious hidden dangers were effectively avoided by measures of preventing rock burst. The achievements to research have important directive significance to the exploitation of whole Juye coalfield.
