Abstract
Stopping compsn. of plastic consistency for stopping holes, lining pit roofs, for closing off mine workings, etc. and for stopping openings around blasting explosions in mines, consists of a malleable material placed in an impermeable envelope under vacuum. The malleable material is esp. a plastic clay and the envelope is a heat shrinkable plastic. The clay is prepd. in the form of a single block, esp. a round cylinder, and the cylinders are arranged in layers in the hole to be stopped. Larger holes can be filled with larger volume masses e.g. in the form of a cushion or a mattress. It is unnecessary to transport concrete blocks into mines to close off old workings and cement them together. Clay bodies adhere to the sides of the openings preventing escape of gas, or recoil of explosive in blasting. They stick to loose rock when used for stopping or lining, preventing dangerous rock or stone falls. The clay blocks are easy to prepare and handle.
