似膏体充填开采防止高承压底板水突出研究
On preventing the high pressure water-inrush from floor with paste-like backfill mining
摘要
Abstract
Studies on the paste-like backfill mining system and the floor failure depth of working faces were carried out in the working face 81006 of Caozhuang coal mine to prevent water inrush from floor karst aquifer. The new type of backfill material made up of cementitious material, coal waste and ash was developed. The backfill mining system was divided into the ground backfilling system and the un-derground system. The system achieves automatic control of material’s addition, mixing and transporta-tion. Double-block leak hunting in drill was applied to measure the floor failure depth in the backfill mining face (working face 81006) and the mining face by caving method (working face 8812). It turns out that the past-like backfill mining has a significant effect on decreasing floor failure depth caused by mine pressure. Based on the“lower four-zone”theory, we analyzed the reducing mechanism of floor damaged depth caused by underground pressure under the condition of paste-like backfill mining, prov-ing that the paste-like backfill mining is the effective measure to prevent high pressure water-inrush from floor.关键词
