    • In the mining of minerals from the earth, it is necessary to drill deep bore holes typically between 3000 and 6000 feet in the earth. In order to protect those entering the hole for additional mining operations, after drilling the hole, the hole is lined with a stack of specially constructed lining segments. These segments are formed of either prestressed concrete or steel. The segments are lowered one at a time into the bore hole so as to build up a stack within the hole, thereby lining the hole. The segments are carried to the hole on a transporter and then lowered by the transporter into the hole. Guide cables are threaded through guide conduits provided within the segments so as to maintain the orientation of such segments during the operation. The weight of the segment as it is lowered is supported by fluid, normally the drilling mud, that fills the hole and the transporter until the segment comes into contact with the top of the uppermost segment on the stack of those segments already placed into the hole. Grout is then placed between the lining segments and the inner wall of the bore hole. The grouting process is periodically carried out after every few segments have been placed into the hole. After the lining operation has been completed, the miners can enter the bore hole for other mining operations.
    • 在从地球开采矿物时,有必要在地球上钻一般在3000和6000英尺之间的深孔。 为了保护进入钻孔的人进行额外的采矿作业,钻孔后,孔内衬有一堆特殊构造的衬里段。 这些段由预应力混凝土或钢制成。 这些段一次一个地下降到钻孔中,以便在孔内形成堆叠,从而衬套孔。 这些片段被运送到运送器上的孔中,然后由运送器下降到孔中。 引导电缆穿过设置在段内的引导管道,以便在操作期间保持这些段的取向。 当下降的段的重量由流体(通常是钻井泥浆)支撑,其填充孔和运输工具,直到段与已经放置在孔中的那些段的堆叠上的最上段的顶部接触 。 然后将灌浆置于衬里段和钻孔的内壁之间。 灌浆过程在每几个细节已经放入孔中之后定期进行。 矿井完成后,矿工可进入钻孔进行其他采矿作业。

    • Minerals, in particular coal, that have been deposited in layers or along seams in the earth can be mined utilizing a large diameter bore hole drilling equipment. With the drilling equipment stationed on the surface of the earth, a drilling member is drilled down into the earth along the seam of the mineral deposit. If the mineral deposit extends at an angle to the earth, i.e. less than 90.degree., the drilling operation is conducted so as to drill at a similar angle to the earth. As the mineral deposits are broken up during the drilling operation, the broken fragments are removed from the drilled hole. After drilling has occurred for a certain distance in a forward direction, a creeping effect is induced in portions of the side walls of the drilled hole. The drilling member is then retracted from the drilled hole in such a manner so as to drill out any mineral fragments in the hole of the drilling member. These mineral fragments are then removed from the hole as the drilling member is retracted. The removal of the mineral fragments can best be accomplished utilizing an hydraulic flow mechanism for circulating fluid through the drilling member and removing the mineral fragments as they are drilled.
    • 利用大直径钻孔设备可以开采已经沉积在地层中或沿着接缝的矿物,特别是煤。 随着钻井设备驻留在地球表面,沿着矿床的接缝将钻孔构件向下钻入地球。 如果矿床与地球成一定角度,即小于90°,​​则进行钻孔操作以便以与地球相似的角度钻孔。 由于矿物沉积物在钻井操作期间被破碎,破碎的碎片从钻孔中移除。 在向前方向发生一定距离的钻孔之后,在钻孔的侧壁的部分中产生蠕变效应。 然后钻孔构件以这样的方式从钻孔中缩回,以钻出钻孔构件的孔中的任何矿物碎片。 然后当钻孔构件缩回时,这些矿物碎片从孔中移除。 矿物碎片的去除可以利用液压流动机构来完成,该液压流动机构用于使流体通过钻孔构件循环并在钻探时去除矿物碎片。

    • A building roof monitoring system that includes a fiber optic filament positioned between a water barrier layer (e.g., roof membrane) and a roof substrate layer of the building roof. The fiber optic filament may be part of a sensing layer that includes the fiber optic filament carried by a water transport layer configured to draw water coming into contact with the water transport layer into contact with the fiber optic filament. An optical analyzer injects laser light into the fiber optic filament and detects changes in propagation of the laser light through the fiber optic filament indicative of water coming in contact with the fiber optic filament to detect a roof leak. A response system including a controller, alarm or remote communication unit operatively connected to the optical analyzer responds to the roof leak detected by the optical analyzer.
