回采工作面过断层方法与跳采实践

摘要

Taking 2228 working face as the research subjects ,the author introduces the crossing fault methods for different faults and elaborates the practice on crossing fault by skipping mining ,w hich indicates the key of cross‐ing fault by skipping mining lies in the support of middle roadway ,the ventilation at working face and the joint of open-off cuts .%合理选择过断层方法是保证回采工作面安全、高效开采的关键。以2228工作面为研究对象，介绍了不同断层应采取的过断层方法，并以D F7断层为研究重点，阐述了利用跳采过断层实践。由该跳采过断层实践可知，跳采过断层的关键在于中间巷的支护、工作面通风和切眼的对接，该跳采过断层实践为矿井跳采过断层积累了经验。
