Study On The Support Technology And Its Application For Steep Hard Thick Coal Seam

According to the geological conditions of Luxin coal mines, For the characteristics of hard thick coal,proposed Steep hard thick Coal Seam support technology and its application,coal mining technology and supporting equipment were taken countermeasures to protect working security. Through the analysis of surrounding rock relations about the level face, Steep face, hard coal face and so on, On the face support equipment-Hydraulic Support for the selection, design, support strength calculation and verification,and also analysis the movement of Hydraulic Support, reliability and stability, the design of Hydraulic Support’s structure completely for the characteristics of Steep thick coal seam,for it is very adaptable. Through long-term industrial tests, analysis the comprehensive test data, testing the pressure on the mining field and doing the full examination for the Hydraulic Support’s structure performance, the supports and protections and the movement stable performance improved the Steep hard thick coal seam face support theory and application practice.
