2 #0183;#32;Contour mining is commonly practiced where a coal seam outcrops in rolling or hilly terrain. Basically, the method consists of removing the overburden above the coal seam and then, starting at the outcrop and proceeding along the hillside, creating a bench around the hill.

Aspects of mining methods selection in both, open pit and underground mining operations, depend on key environmental and economic factors including: Geological characteristics of the ore body, including the geotechnical competency of host rocks and the spatial distribution of ore and waste.
ADVERTISEMENTS: In this article we will discuss about the types of drilling methods used in mining. The types are: 1. Percussive Drilling 2. Rotary Drilling. Method # 1. Percussive Drilling: In this method which is the oldest one of drilling, the hole is drilled by striking
appropriate mining method is selected based on technical, economic, and environmentally accountable considerations. The first step in selecting the most appropriate mining method is to compare the economic efficiency of extraction of the deposit by surface and underground mining methods .

1. Underground Mining Methods Classification of Underground Mining Methods Mineral production in which all extracting operations are conducted beneath the ground surface is termed underground mining. Underground mining methods are usually employed when the depth of the deposit and/or the waste to ore ratio (stripping ratio) are
Steel sector require coking coal of ash% within a range of 18+ whereas power sector require noncoking coal of ash% within a range of + Why Indian Coals contain High Ash? Indian coals contain high ash content because of its formation thro drift origin.
Under ground mechanized mining methods. Drop Raising in Mining (VCR) Methods of Stopes ( Extraction of Ore). Hindustan Copper Limited has addressed the complex raising operation in mining and developed and implemented Drop Raising techniques at 80 meters intervals which improved safety and led to faster and higher productivity.

#0183;#32;Surface mining is done in five ways: Strip mining Strip mining is the most common surface mining method used to mine coal and lignite. The process is done by removing a strip of overburden before mining a seam of mineral. Strip mining is done only when the
There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are
