Abstract
A plug for a void in a mine to divert water having a rigid closed cell foam which fills the void. The rigid closed cell foam having a plurality of pipes disposed within the foam. The pipes distributed throughout the void. The pipes are positioned in the foam so the pipes are staggered in length vertically with respect to various heights in the void, and the pipes are positioned in the foam every 4′ to 6′ horizontally with respect to the void. Each pipe has a mixing stick. A method for diverting water from a void in a mine.
Claims11
A method for forming a void in a mine comprising the steps of:
- adding a catalyst to a single component material;
- providing the single component material with the catalyst to a pump which pumps only the single component material with the catalyst;
- supplying air to the pump at a minimum of 90 psi while the pump is pumping the single component material with the catalyst through a first hose attached to a first port of a y fitting;
- supplying water at a minimum of 60 psi through a second hose to a second port of the y fitting so the water and single component material with the catalyst merge in the y fitting to create a product, the catalyst used being a function of ambient temperature about the void and the water temperature;
- and
- placing the product with a third hose that extends from the y fitting on the outer most areas of the void and moving the product to the middle of the void, where the product expands when the product releases into the void from the third hose and cures to a rigid closed cell foam to form a plug in the void.
A plug for a void in a mine comprising:
- a rigid closed cell foam which fills the void having a plurality of pipes disposed within the foam, the pipes distributed throughout the void, the pipes are positioned in the foam so the pipes are staggered in length vertically with respect to various heights in the void, and the pipes are positioned in the foam every 4′ to 6′ horizontally with respect to the void.
