dip: a miner’s word not found in the mining act. The term there used is downward course, which is synonymous with dip. The direction of the vein or lode as it goes downward into the earth is called the dip. It may vary from perpendicular to the earth’s surface to an angle perhaps only a few degrees below the horizon. The same vein or lode may have different dips.  1, record 3, English, - dip%20face

[A mining method in which] the ore is excavated in open stopes, retreating from one end of the stope toward the other. The orebody is developed first by a series of sublevel drifts above the main haulage level. The sublevels are connected by a starting raise at one end of the stope and by a passageway raise for entrance to them and the stope face at the other end. Chute raises connect the haulage level to the lowest sublevel, at which the tops of the chute raises are belled out to form mill holes. Beginning at the starting raise the ore is benched down from the sublevels; the broken ore falls into the mill holes, where it is drawn off through the chutes. The stope face is kept nearly vertical as it is benched backward toward the passageway raise.  6, record 4, English, - sublevel%20stoping

Wide-vein deposits contained within competent waste rock and at vertical or steeply angled inclination permit use of a method called sublevel stoping. This method can be likened to the month on the page of a calendar, with the top and bottom edges representing the main haulage levels where all of the ore from above is removed. Each row of weeks on the calendar page represents sublevels started from the right-hand edge raise toward the left-hand edge raise widened to full-vein width. The sublevels starting at the bottom left day of the calendar page are drilled with long holes in a circle around the opening, then blasted in one large blast, removing a segment of rock ... along the sublevel. It would be like removing one day of the week from left to right, bottom to top of the calendar page, and dropping it to the bottom edge, where previously installed chutes funnel them to the train or load-haul-dump unit for haulage to the shaft.  2, record 4, English, - sublevel%20stoping
