Zusammenfassung: | In excavations, such as mines, supports are needed to prevent rock falls. Structural beams provide the main support in the excavation to prevent major rock falls. However, between the main beams, minor rock falls can still occur. To provide structural support between the main beams, a polymeric structural support membrane can be applied. The membrane includes a polymer that is the reaction product of a monomer, an initiator, and optionally a crosslinking agent; and a self-extinguishing agent. The membrane can be applied by spraying, brushing, or rolling.
En excavaciones, como minas, son necesarios soportes para evitar la caida de rocas. Las vigas estructurales proporcionan el soporte principal en la excavacion para evitar caidas de rocas mayores. Sin embargo, entre las vigas principales, pueden ocurrir aun caidas de rocas menores. Para proporcionar soporte estructural entra las vigas principales, puede ser aplicada una membrana de soporte estructural polimerica. La membrana incluye un polimero que sea producto de la reaccion de un monomero, un iniciador, y opcionalmente un agente reticulante; y un agente autoextinguible. La membrana puede ser aplicada por rocio, brocha o rodillo. |
