Final answer:

Room and Pillar Mining is suitable for horizontal bedded or tabular ore bodies with moderate thickness and is commonly used for non-metallic minerals like coal and limestone.

Step-by-step explanation:

Room and Pillar Mining is appropriate for bedded or tabular ore bodies that are relatively horizontal with moderate thickness and uniform in deposit. This mining technique involves carving out rooms in the ore body while leaving pillars of ore to support the mine roof. When the mining activity is completed in a room, it is abandoned, and the mine moves on to build the next room leaving the pillars as structural support. This method is typically used for the extraction of coal, salt, potash, limestone, and other non-metallic (soft) minerals. Room and pillar mining is chosen for these types of ore bodies because it allows for the safe extraction of minerals without extensive excavating while also minimizing the subsidence of the surface.
