Room and pillar is also known as bord and pillar is a mining system in which the mined material is taken out across a horizontal plane while leaving pillars of unscathed material to support the overstrain leaving open regions or rooms underground.
A considerable amount of expenditure and information is required to define a coal deposit, design the mine, then extract and prepare the coal for the customer. The mine operations have conceptual plans for nearly 30 years and detailed plans covering periods of 5-15 years, where the detail is sufficient to allow planning of overburden removal and coal haulage.

· Evaluation of blast efficiency in quarrying of aggregate stones is one of the most important decisions that should be made by quarry operators for productivity assessment. The regulatory authorities also evaluate blast efficiency for environmental safety compliance. In carrying out this task, there is usually a conflict of interests between the quarry operators and the regulatory authorities ...
· Mining equipment is unable to precisely select the material to be extracted; thus, some partings are expected to be included as the coal is mined (dilution). This dilution can increase depending on the movement caused to the seam during blasting.
· Coal sampling system is used for collecting sample from coal truck, coal railcar, and coal moving stream. Coal auger and coal sample preparation system are the crucial elements for the sampling system. For different kinds of coal, TOP SAMPLER provides different

When the 1969 Coal Mine Health and Safety Act was enacted, U.S. coal production was about 600 million tons with about 60 percent underground mining and 40 percent surface mining. Longwall mining accounted for less than 1 percent of the underground production; room-and-pillar continuous mining accounted for about 50 percent of the underground production.
This book is intended for use in teaching coal-mine design to undergraduate mining engineering students. The preliminary chapters cover the geology of coal, coal statistics (classification, distribution, resources etc.), exploration and mine planning and development.
