Conceptual Design for a Coal Mine Gob Well Flare
Flare Tip Diameter. The concept design recommends a minimum flare tip diameter of 24 mm (approximately 8 inches) based on the expected gas flow range and the requirements of 40 CFR Flare Height. Based on a kW/m2 (1500 Btu/hrft2) criteria at the base of the stack, the concept design specifies a m (20 ft) overall stack height.

Process design of the Phola coal J preparation plant o
The design of the Phola coal preparation has its roots in the late 1980s when there was a requirement for a plant to treat 8 Mtpa coal from Ingwe's (now BECSA's) adjacent Klipspruit opencast mine at Ogies, Mpumalanga. The mine is part of the South African Witbank Coalfield and accesses the No. 2 and 4 Seams with some 5 Seam material.

Working in coal mines prior to the second half of the 20th century was considerably more dangerous than working in coal mines today. Although considered to be one of the more dangerous trades in industry, coal mining has come a long way in terms of safety and risks. There are now major
Floor design in underground coal mines | SpringerLink
Floor failure and excessive heave in underground coal mines can jeopardize the stability of the whole structure, including the roof and pillars, due to differential settlements and redistribution of stress concentrations. Besides, floor failure is detrimental to haulageway operation and can lead to unacceptable conditions of high deformation. Thus, the design of any underground opening must ...
