The practice of fully-mechanized coal mining for belt of fault in steeply dipping seam
Abstract：In fully mechanized working, the faul is very prone to cause spalling and roof falling accident, especially in the qualita- tive difference of fault and steeply dipping seam , the more difficult conditions bring great pressure and more difficulties to the safety production, gequan coal mine, through long and short range of chemical grouting and strengthening measures of fully - mechanized coal mining technology , realizing the Safety mining and passing the belt of fault successful, avoiding the Fully mecha- nized moving and roof accidents, acquiring the precious experience and practice.
