Abstract: A continuous mining machine employs a chain conveyor consisting of two separate chains with one-sided flights. The axes of the chain sprockets are located within the vertical plane so that the chains run within the plane generally parallel to the mine floor. The chains have universal links so they can change direction within the vertical plane as well. This arrangement allows substantially better special configuration than the present chain conveyors and the flights of the chains provide loading function, thus eliminating the need for the loader.
Abstract translation: 连续采矿机采用链式输送机，由两条单独的链条组成，具有单面航行。 链轮的轴线位于垂直平面内，使得链条在平面内大致平行于矿层运行。 链条具有通用连接，因此它们也可以在垂直平面内改变方向。 这种布置允许比现有的链式输送机大得多的特殊构造，并且链条的翼片提供加载功能，从而不需要装载机。

Abstract: In situations where pressurized unsaturated brine or other unwanted liquid seeps through incompetent or soluble rocks, a pair of dams are constructed within a passageway, and the interface between the dams and the host rock is sealed. Thereafter, a hydrophobic liquid is injected under pressure within the passageway between the two dams thus impregnating the microfracture system within the host rock. A monitoring installation is used to sample the area on the flood side of the first barrier. This flood isolation method is also useful in containing other wastes such as in nuclear repositories.

Abstract: Various high pressure isolation structures are operative to prevent brine or other unwanted liquid from seeping through incompetent or soluble rocks. In one embodiment, a pair of barrier dams are constructed in spaced relation within an underground passageway, and the interface between each dam and the host rock is sealed. A hydrophobic liquid is introduced under pressure into the passageway between the dams so as to impregnate the microfracture system within the host rock. A monitoring installation may be employed to sample the area on the flood side of the upstream barrier dam. Alternate embodiments of isolation structures in the form of expandable bulkheads may be employed to effect accelerated rock repressurization so as to close the microfractures either individually or in combination with another barrier dam with hydrophobic liquid.

Abstract: There is described an extensible belt take-up and storage device for use in an extensible belt conveyor system. The device overcomes the shortcomings of the prior art by being very compact and by having a configuration such that almost all the stored belt can be let out to the conveyor system. To accomplish this first and second sets of rollers are mounted on a fixed and on a movable frame respectively and the rollers are mounted parallel to each other and inclined at an acute angle to the horizontal axis of the device.
