摘要
鲍店煤矿在综采放顶煤工作面采用双巷交错布孔（上巷二孔，下巷一孔）随采随注法进行煤层注水，提高了降尘率，对解决庄水难、顶煤垮落难及煤体降温等均有较好效果。
ater infusion was carriedout at fully mechanized caving face at Bao-dian Mine with cross infusion holes(twoholes in tail gate and one in main gate)and by means of infusing while mining,which raises the efficiency of dust removaland effectlvely solves the problems such ashard infusion, difficult roof caving andcoal body cooling.
