摘要： An explosive-resistant mine seal (2) is provided, which includes a pair of block walls (14, 16). An adhesive (22) is provided between adjoining surfaces of the blocks (20) where the adhesive (22) has greater strength properties than the blocks (20) themselves. A core member (18, 18′) is provided between the two walls (14, 16) and is bound thereto. The adhesive (22) may be coated over the walls (14, 16) to increase the strength of the mine seal (2).

摘要： A support for use in mines and other underground workings is provided comprising a flexible inflatable bag configured for receiving a pumpable load-bearing material. A reinforcing material is provided for supporting the bag when the bag is filled with the load-bearing material. The reinforcing material can include reinforcing plates, rings, bands or barrels positioned about the outer periphery of the bag. Alternatively, the support can be formed from a plurality of stackable barrels that are filled with load-bearing material but without the inflatable bag. The barrels can include internal reinforcing or cladding material at spaced locations along the barrels to define controlled deflection zones. According to another design, the support can be designed to be extensible. The support is inexpensive to transport, can be erected on-site and has a reinforced structure with residual yield strength. A method for supporting a mine or other underground workings is disclosed.
摘要翻译： 提供了用于矿井和其他地下工作的支撑件，其包括构造成用于接收可泵送的承载材料的柔性充气袋。 提供一种加强材料，用于当袋被承载材料填充时用于支撑袋。 增强材料可以包括围绕袋的外周定位的加强板，环，带或桶。 或者，支撑件可以由填充有承载材料但不具有可充气袋的多个可堆叠的桶形成。 桶可以在沿着桶的间隔位置处包括内部加强或覆层材料，以限定受控偏转区域。 根据另一种设计，支撑可以被设计成可扩展的。 支撑件运输成本低廉，可现场直立，并具有残余屈服强度的加固结构。 公开了一种用于支撑矿井或其他地下工作的方法。
