The room-and-pillar goaf is filled with a frozen ice body. Roadways and mining faces are arranged in the frozen ice body. Coal cutter cuts the residual coal pillars and the frozen ice body. With the advancing of the mining face, the residual coal pillars are gradually recovered and melted water after the cutting is pumped out.

Abstract: This invention is an underground irrigation system for turf, trees, vegetables, and/or shrubberies with special clog-proof underground emitters and special in-line containers or vessels that are used to apply liquid and granular additives, such as fertilizer and weed control additives. This underground irrigation system functions for many years without issues such as clogs, broken emitters, punctured lines, or leaks. The only service requirement of this irrigation system in best mode is the replacement of batteries every two years or so. This invention also provides the ability to add liquid and/or power additives that are required to keep turf, trees, vegetables, and shrubbery healthy and free from weeds and other invasive plants. As with all underground irrigation systems, this invention saves a substantial amount of water as compared to any type of above ground irrigation system because there is no water run-off, no leaks, and no evaporation.
