Zusammenfassung:	FIELD: mining industry, particularly for underground ore deposit mining. ^ SUBSTANCE: method involves mining the deposit by rooms in which raise drills are bored; drilling wells arranged in fan-like array and cutting mineral. Raise drill is deepened in lower wall rock and bottom thereof is covered with metal sheets. Ore is cut in parts simultaneously with rock excavation in the range from raise drill ground to room ground at original ore mass slope angle. ^ EFFECT: increased cutting intensity, reduced ore losses in lower wall rock at room fender due to impoverishment thereof. ^ 3 dwg
