The document discusses the challenges of extracting coal from underground mines that have been developed with pillars, by using opencast mining methods. It notes that as opencast mines deplete virgin coal seams, developed underground pillars will be an important future source of coal. However, extracting coal from these areas poses risks like coal dust explosions, fires, and miners falling into unstable voids ("pot holes"). The document outlines safety guidelines from DGMS for working in areas with underground development, including maintaining minimum partings above galleries, controlled blasting procedures, and isolating active underground areas. It also describes the processes used to systematically extract coal from developed pillars, including delineating zones of increasing risk and ensuring ground control through compaction before
This document discusses different types of entry systems used in opencast mines. It describes single, double, triple, and spiral entry systems. Single entry systems are suitable for short pits up to 1000m with low production. Double entry systems are used for pits up to 1500-2000m with medium production. Triple entry systems have entries on both sides and in the center for large, high production pits over 2000m. Spiral entry systems are used for pits on hilltops or deep pits. The appropriate type of entry system depends on factors like pit length, production levels, transportation needs, and overall economics.

Conversion of Underground Mine to Open Cast MineAbdul Mujeeb
This document discusses the conversion of underground coal mines to opencast mines. Underground mining is becoming uneconomical, so coal reserves trapped in underground mine pillars need to be extracted through opencast mining. The key steps in conversion involve isolating underground workings, conducting surveys of workings, dividing the mine area into safety zones, compacting galleries through drilling and blasting, and extracting coal while preventing collapse of underground structures. Attention to surveying, drilling patterns, charging, blasting procedures, and marking excavated areas is important to ensure safety during conversion. The Gouthamkhani opencast project is provided as a case study, with details on its reserves, production, geology, machinery, and mine plan.

The continuous surface miner is a modular machine that operates by using a rotating cutting drum fitted with cutting tools to cut material from rock formations in layers. As the crawler-mounted machine moves forward, the cutting drum rotates against the direction of travel to cut the material. The cutting tools transport the mined material toward the center of the drum where it can then be loaded onto conveyors. The mined materials can be directly loaded onto trucks, discharged to the side to be mixed, or deposited as a windrow between the miner's crawler tracks.
