In order to ensure the safe mining of 12305 fully mechanized coal caving face while passing finished mining roadway in Jindi Mine, the super high-water material was chosen to fill the roadway based on the comprehensive comparison. The characteristics of this material, including strength characteristics, setting time and fluidity, were introduced in detail. Combined with the actual conditions of the roadway, the material filling body was directly entered into the roadway by the way of self flow. Through the use of super high water material filling, the safe recovery of 12305 working face was ensured, and achieved significant economic and social benefits.
