coal reserves (286 BT) and is the third largest coal-producing country in the world. Though coal demand has risen by around 9% over the last four years (FY 2006-07 to 2010-11), production which grew by around 5% during the same period has not kept up with it. The domestic industry can supply only 534.53 MT coal as against the demand of 696.03 MT in
iron ore mine and a coal mine and the hazards were identified and risk analysis was carried out. The different activities were divided in to high, medium and low depending upon their consequences and likelihood. The high risks activities have been marked in red colour are un-acceptance and must be reduced.
Coal is one of the most essential resources of a country. It is widely used for power generation and as a raw material in the industries. India ranks third in coal production. However, the country has to import coal in order to meet the rising demand for coal. In India, coal mining is conducted using two methods: underground and opencast methods. The underground method is suitable …

The opencast mining accounts for about 95% of total coal production in India (DGMS Report, 2016). This has resulted in the opencast mines going deeper day by day with the maximum stripping ratio being planned currently looking upto 1:15, at a depth of about 500 m. The benefit of an opencast mine largely depends on the use of the steepest
the demand of coal in the year 2016-17 was estimated 884.87 MT whereas the domestic availability of coal was estimated 724.71 MT. Here, the gap of 160.16 MT was projected to meet through the imports (Satyanarayana et al. 2018). In this regards, open cast mining technology can play a vital role to full fill the demand of estimated coal ...

The coal seams are near the surface and therefore an opencast mine is preferential. The first intersected coal seam is approximately 14.61 m below the surface, with an average parting thickness of 0.97 m between the 2 and 2L Seams, and a total coal thickness average of 6.09 m thick. Mining operations will last approximately 29 months.

The opencast coal mining technique is used in areas were the coal reserves are scattered in shallow and thin seams and cannot be extracted by deep mining methods (Beynon et al., 2000). The opencast process starts with exploration activities to identify where there are deposits of coal and what is the depth of the seams.
The hard coal has a large ash content (44 per cent) and thus coal dressing is an imperative. The coal dressing processes entail the formation of dumps and slurry ponds while the waste waters are discharged into the Jiu River. The above mentioned fact show that mining activity has a …

The time in which the mine remains operational, from start-up to mine closure. The average rate at which mining takes place within a certain time period (normally per annum). The mining rate can refer to coal extracted per annum or to the waste stripped per annum. A mining practice in which the higher quality coal is mined first in the mine life.
Opencast coal mining (OCM) is considered to be officially introduced in the UK in 1942 as an emergency measure during WWII (Peart & Rutherford, 1986) and shortly after that put into practice in South Wales in 1943. However, the first "official" opencast coalfields were opened in the autumn of 1941 (Beynon et al., 2000).
The passage of the Federal Coal Mine Health and Safety Act of 1969 established respirable dust exposure limits, dust sampling requirements for inspectors and mine operators, a voluntary x-ray surveillance program to identify CWP in underground coal miners, and a benefits program to provide compensation to affected workers and their families.

Drilling and blasting are the major unit operations in opencast mining. Inspite of the best efforts to introduce mechanization in the opencast mines, blasting continue to dominate the production. Explosives contribute currently about 5% of the direct cost of production and if the aggregate cost of drilling and blasting is taken together, this ...
Open cast mine has significant impact on land ... For instance, a capacity of 10 million-tons opencast coal mine in 20 years has a potential to destroy around 800 ha of land 2) Air - Mainly in the form of Fugitive Dust. Most mining operations generate dust such as Drilling, blasting, Vehicles movement on haul roads, Collection, ...
Augering can be regarded as a supplementary method for open cast mining in cases when coal seams in the highwall would otherwise remain unmined (unless recoverable by underground methods) or when rugged terrain would preclude economic stripping by conventional surface methods. Quarrying of dimension stone and highwall

There are many advantages to the open pit mining method, namely: 1. Full visualization of exposed orebody and negligible ore loss. 2. No ore reserve is blocked, except crown pillar at the ultimate pit bottom to continue to underground mining. 3. Greater concentration of operations, better grade control, and blending. 4.
