The underground ore rock conditions are extremely unstable in Jinfeng Gold Mine so that relatively large exposed area is not allowed.Therefore,the test applied upward horizontal slicing approach and ungraded tailings cemented filling mining method.The paper introduced the cutting and preparation engineering,approach layout form,stoping technology,filling process and industrial application of the method.Field application results show that with introduction of large amounts of mining & excavation,transportation,supporting equipment,adoption of highly mechanized operation means,and classified support for all underground projects,the upward horizontal slicing approach and ungraded tailings cemented filling mining method can achieve the goal of safe and efficient stoping,with stope production capacity about 200 t/d,mining loss rate 8 %,ore dilution rate 10 %.The performance of the method is good and it can be used as a reference by similar mines.
