New Scheme of Roadway Layout in Longwall Top-Coal Caving System

摘要

Based on mining design theory and practice, a production system of stagger-arrangement roadway in thick seams is put forward for the first time. The system can comprehensively solve the problems in longwall top-coal caving system, such as raising recovery ratio, discharging gas, preventing spontaneous combustion and improving the upkeep of roadway etc.
