为了掌握特厚复杂煤层综放开采工作面煤壁片帮规律,在分析综放面回采工艺和机械设备的基础上,通过观测工作面周期来压期间和非周期来压期间煤层推进度与片帮深度及片帮率的关系,得出了采面片帮深度和片帮率的分布规律,为改进回采工艺和采面安全生产提供了可靠的科学数据.“,”In order to master the special complex thick seam coal wall rib spalling law of fully mechanized working face, based on the analysis of the fully mechanized caving stoping technology and mechanical equipment, through observation of the relationship between coal seam advancing and rib spalling depth and rib spalling rate during periodic working face with pressure and non-periodic working face with pressure, mining face rib spalling depth and rib spalling rate distribution law were concluded, which provided a reliable scientific data to improve the stoping technology and mining face safety production.
