Application of highwall mining system in weak
Almost all the coal is produced from open cut mines in Indonesia. As a consequence of open cut mine application, a great deal of coal is left out in the highwalls of the mined-out pits. Highwall mining The following are the SFs and design criteria typically used in designing a highwall mining excavation area: A highwall mining panel should not exceed 20 openings between barrier pillars. Web pillar SF ≥ 1.6 for normal operations. Web pillar SF ≥ 2.0 for protection of critical structures.

b) In room and pillar mining, the recovery rate is about 40–60%. Whereas in long wall mining method, the recovery rate is as high as up to 75%. c) In thick coal seams, long wall mining method is used, whereas in thin coal seam, room and pillar method is used. It has thickness ranging from 0.75 to 4.0 m.For the first quarter, EQT reported $580 million in free cash flow that can be used to pay off debt or be delivered back to shareholders, more than double the $259 million reported in the first quarter of 2021.

Highwall Mining in India SpringerLink
Highwall mining is a proven technology in USA and Australia to extract the blocked coal in thin non-workable seams and the coal blocked in the highwall of opencast mines. In USA, highwall mining contributes about 4.0 % share of total coal production. In India, the highwall mining is in the nascent stage. So far only two highwall mining areHigh wall mining is a remotely controlled mining process that isolates coal from the base of an exposed high wall. The technique has a low capital cost and less production time than a full underground mine. High wall mining can also produce more than 1M tonnes per system annually. This method has frequently been used in Australia, the U.S., andThe Assay Explains Surface Mining
