深部“孤岛”工作面通防保障技术研究

由于矿井深部煤层具有"三高一扰动"的特点,进而在一定程度上使得深部安全开采问题逐步突出。受深部煤层煤质松软的影响和制约,在一定程度上为了防止生产和连续工作面之间产生干扰,通常情况下,通过"孤岛"布置方式确保生产的安全进行。采空区以及相邻采空区因"孤岛"布置进而导致容易发生通防事故。因此,通过对深部松软煤层"孤岛"综放面通防保障技术进行研究分析,进而在一定程度上对于安全开采具有重要的现实意义。

Study of Ventilation,Gas ,Dust and Fire Security Technology for Deep ＂Islet＂ Working Face

Due to the ＂three high and one disturbance＂ characteristics of deep coal seam, safety problems in deep exploitation are serious. Influenced and restricted by the soft coal quality in deep coal seam, in order to avoid interference between production and continuous working face, ＂islet＂ layout is commonly used to ensure safe production. The goaf and adjacent goaf are easy to cause ventilation, gas, dust and fire accidents because of the ＂islet＂ layout. Therefore, this article studies and analyzes the ventilation, gas, dust and fire security technology in deep coal seam ＂islet＂ caving face, which is of important practical significance for safe mining.
