Strip mining face recovery improve according to measures optimization practice
条带综放工作面端头不易放煤，回收率低。为提高条带工作面的回采率，采取了端头放煤、超前退锚索锚杆措施、后部放煤工序优化、初采停采放煤距离延长等针对性措施，有效地提高了煤炭回收，提高了煤炭回收率。
條帶綜放工作麵耑頭不易放煤，迴收率低。為提高條帶工作麵的迴採率，採取瞭耑頭放煤、超前退錨索錨桿措施、後部放煤工序優化、初採停採放煤距離延長等針對性措施，有效地提高瞭煤炭迴收，提高瞭煤炭迴收率。
조대종방공작면단두불역방매，회수솔저。위제고조대공작면적회채솔，채취료단두방매、초전퇴묘색묘간조시、후부방매공서우화、초채정채방매거리연장등침대성조시，유효지제고료매탄회수，제고료매탄회수솔。
Strip of full - mechanized caving mining face not easily end caving, recovery rate is low. To improve the bands recovery rate, take the end put coal, advance the measures, the refund anchor caving process optimization, in the coal mining stop put distance extended and corresponding measures, ef- fectively improve the coal recovery, improve the coal recovery.
