黑沟煤业探索研究“三软”(软顶、软底、软煤层)条件下的高效综采模式,填补了区域类似条件下技术空白,被山东省企业技术创新促进会评为2011年度矿井技术创新一等奖。黑沟煤业创新推出的复合顶板“三软”煤层高效综采模式,其关键在于对围岩技术的有效控制,主要通过建立围岩控制机理、监测技术体系,进一步了解和掌握复合顶板失稳破坏机理,科学界定工作面超前支承压力影响范围,优化设计相邻工作面
Heigou Coal Industry explores and studies the “Three Soft” (soft top, soft bottom, soft coal seam) under the conditions of efficient and fully mechanized mining mode to fill the technical gaps under similar conditions in the region was Shandong Province Enterprise Technology Innovation Association as 2011 Annual Mine Technology Innovation Award. The key to effectively controlling the surrounding rock technology lies in the innovative high-efficiency fully mechanized mining mode of composite roof and “three soft” coal seam developed by Heigou Coal Industry. The key is to establish and control the surrounding rock control mechanism and monitoring technology system to further understand and master the composite roof Destabilization and failure mechanism, scientifically define the influence range of advance supporting pressure of working face, and optimize the design of adjacent working face
