Distribution Laws and Control Technology of 8^# Coal Roof Cracks in Shaping Mine

Roof characteristics of coal seam have a major impact on roadway design, working face roof management. The roof crack occurrence characteristics and distribution laws of 8^# coal in Shaping Mine was determined by mathematical statistical analysis, geological analysis and drilling peep other methods. The 8^# coal seam roof crack zone control technical measures were proposed during the excavation and recovery.
