The usage of coal in the Indian market scenario plays a vital role in power generation and other industries The application of continuous miners in India coal mining could be a good choice for the improvement of coal production and productivity Also the utility of continuous miners system in underground coal mining is appropriate technology
mining[1] and the rest of the coal is produced from underground coal mining With t he high rate of extraction from opencast mining and the increase in the number of new open cast mining fields
Mechanisation of Coal Mines is a continuous process However the degree of mechanization varies from mine to mine In CIL out of the 271 underground mines 227 mines are operating under various methods such as fully mechanized PSLW packages Shortwall packages CM with Mass Production Technology Semi mechanized bord and pillar mining with LHD & SDL and
Mancherial The Singareni Collieries Company Limited SCCL Srirampur Area General Manager B Sanjeeva Reddy said that production would go up with the help of modern mining machines He formally inaugurated two Side Discharge Loaders SDL at RK5 and RK6 underground mines in Srirampur on Monday Each machine cost Rs 50 lakh
In the underground coal mine drainage process it is a pure lag process from starting the pump motor to discharging the water of the sump to the drainage pipe For the drainage pipe the water flow gradually increases to a steady level this changing process is an inertial process Therefore the drainage system of the underground coal mine can
Underground Coal Mine in India — Bijay Kishore Abstract The proportion of coal production from underground mine in India is around 8% only which is very less compared to leading coal producing countries in the world It shows that our major focus dominance and reliance have been on opencast mining in meeting coal/energy demand of the country
The continuous miner technology CMT is being adopted extensively in underground coal mines of India as mass production technology This technology potentially eliminates the two unit operating namely the drilling and blasting This elimination helps for better strata control and avoids the drillers working in unsafe conditions maybe under the loose coal
Underground coal mining causes strata movement and damage which has further led to releasing of coal bed gas and strata water Water and gas are the main origin of coal mine accident; meanwhile loss of underground water could cause destruction of surface vegetation and ecological environment especially in west arid and semi arid area of
The Indian coal mining industry has witnessed a persistent decline in under ground coal production over the years with more emphasis on opencast mining The trend of coal production from mines
The article is arranged as follows Characteristics of data related to coal mining are introduced in Section 2; advantages of the IoT big data and cloud computing in processing mining data are analyzed in Section 3; establishment and application of the dynamic platform is presented in 4 Platform design and technical features 5 Platform application and discussion

11 Details of LHD • an electro hydraulic powered underground mining equipment • used to collect the coal haul upto the discharge point of hopper/chain conveyor/belt conveyor located within 100 m from the coal face and to dump on it • 50 HP 811 Model Motor and 100 HP 912E Mode Motor •Three forward and three reverse speeds • The working
The document appears to be a practice test for an underground coal mining exam containing 100 multiple choice questions covering various topics related to underground coal mining such as mine safety mine development mining methods rock mechanics ventilation and more Sample questions are provided relating to topics like mine inspection frequency
In an underground coal mine most successful and economical approach to support the underground structure is roof bolting technology The most preferred method of working in In the conventional method of mining LHD/SDL machine has been used to operate the gallery size up to m The present practices on support design considering two
Unexpected occurrence of uneven breakdowns and their consequences have a significant influence on the equipment life Hence there is a need to discover the motives for the happening of critical potential failures and required repair or replacement action to control Reliability analysis is utilized to approximate the performance of the equipment In this study
In the conventional method of mining LHD/SDL machine has been used to operate the gallery size up to m Primarily the design of roof fall is one of the predominant causes of fatalities in underground coal mines and that trend continues even today Mandal et al 1999 Strata control is a major problem
Coal cutting machines were invented in the 1880 s Before this invention coal was m ined from Modern underground coal mining methods can be c lassified into four distinct categ ories
Coal Belt Somagudem Indaram Coal Belt 6 Borehole density No/ 7 No of coal seams present 8 8 Seams considered for working 5 9 Coal Reserves Geological Reserves MT Extractable Reserves MT Balance Extractable Reserves MT as on 10 Average grade of Coal
A majority of coal mines use conventional mining methods of cyclic development and depillaring using SDL/LHD technologies Fig 3 The major candidates of MPT in underground coal mining are longwall high wall and continuous miner mismatch of geotechnical factors with machine specification foreign suppliers high breakdown
Underground mining requires lot of water pumping to surface which increases cost Because of safety support ventilation and environment costs underground mines are closing down gradually all over the world This innovative paper is based on method studies by computer programming with realistic data With development of electronic control systems
Pillar method by hand section drills and semi mechanization by using SDL s/LHD s The total coal produced from this mine since inception is MT This mine has produced 1 68 965 tonnes of coal during the year 2023 24 Size of the project The total mine take area of GDK 1&3 Incline mine is Out of which is SCCL
Conventional underground coal mining relies upon the use of continuous miners in order to extract coal reserves from underground coal seams In combination with the continuous miners shuttle cars
