CONTINUOUS MINERS 1. Nirbhay Kumar Sinha Roll2013MT0130 BranchMining Machinery Engg. ISM Dhanbad 2. INTRODUCTION : Continuous mineris a machine used for cutting and loading of coal used in underground Board and Pillar mining operation. The JOY continuous minerproduct line has been developed to meet the high productivity requirements of today''s underground mining industry.
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
Continuous miners. Though there are many variations in design, continuous miners mostly consist of five main elements: A central body to carry all other components mounted on some type of drive mechanism to provide mobility (most commonly tracks). A "cutting head" usually rotating drum(s) and/or chains with cutting picks attached A loading mechanism to pick up cut coal and deliver

Lean continuous improvement is a strategy designed to help eliminate waste throughout a company. Waste is anything that doesn''t add value for the customer. In many ways, this continuous process improvement strategy works to eliminate problems rather than directly improve a process. The results are similar, but by taking a wastefocused approach, it is often easier to come up with goals from
