摘要 为保证232201综采工作面回采期间安全过断层,本研究分别在工作面不同的位置设计不同的过断层方式,并对过断层期间矿压进行观测。结果表明,工作面过断层时,周期来压步距为20m左右,工作阻力明显增大,为工作面安全回采提供了数据支撑。 In order to ensure the safe crossing of faults during the 232201 fully mechanized mining face, different faults were designed at different positions on the working face, and the mine pressure during the fault was observed in this tudy. The results show that when the working face passes through the fault, the stepping interval is about 20m, and the working resistance is significantly increased, which provides data support for the safe mining of the working face.
