城郊煤矿超高水材料充填系统设计研究与应用

 为了解放老城区建下压煤，城郊煤矿引进超高水材料充填开采技术，在C2401工作面实施充填开采试验。根据井下实际条件，设计出合理的充填系统，系统生产能力可达280m3/h。经过多次充填实验，结果表明：充填系统操作简便，生产能力大，上料、制浆、输送系统间配合正常，能够实现浆液的连续生产、输送；超高水材料浆液流动性好，适合长距离管路输送，且充后管路易处理；超高水材料充填开采技术是一种新型先进的充填技术，设备初期投资较低，机械化程度高。

The Design Research and Application of Super High-Water Filling System in Chengjiao Mine

In order to mine the coal under the old town, super high-water material filling-mining technique was brought in by Chengjiao mine to do mining test in the coal face of C2401.According to the working conditions under the shaft, a reasonable filling system was designed, whose production capacity can reach 280m3/h. After many experiments of filling, the results show that: The filling system has simple operation method and high production capacity; Feeding, preparing and piping system can cooperate with each other normally; the slurry of superhigh-water material has good liquidity, is suitable for long distance pipeline transportation, and can be washed away easily after filling; filling-mining technique is a new type of advanced filling method, whose equipment has low initial investment and high degree of mechanization.
