Mine Mechanization And Technology Development
Mine Mechanization and Technology Development

This group consists of two Sections; Mine Mechanization and Product, Process and Technology Development.  The mandate and important activities and achievements are described in the Section 1 & Section 2. Each Section consists of members with multidisciplinary expertise and works towards the mine mechanization and product development.  


Section 1: Mine Mechanization

Mandate:
Mine Mechanisation Section aims to develop new capabilities for the mining industry and improve safety, profitability and sustainability in mine design, operation, and closure activities. The primary focus is focused on mechanization and automation of mining activities with the state-of-the-art technologies in mining industry encompassing all methods of coal and non-coal mining (underground and opencast) in India and abroad. The Mine Mechanisation Section facilitates multi-disciplinary research in the following areas:

  1. Investigating and analysing properties and mechanics of rock mass for mine mechanisation with Longwall technology, Shortwall method, and the other continuous mining technologies.
  2. Identifying and applying latest technologies in coal and non-coal mines for higher productivity and safety;
  3. Understanding of human factors in mechanisation and automation,
  4. Applying innovative systems (Embedded based) approach to mechanisation and automation.
  5. Providing training and consultancy services to the industry in the areas of mine mechanisation in coal and non-coal industries

Important Activities:

  1. Geotechnical study for mechanisation with Longwall, Shortwall, and other Continuous mining technologies to extract mineral from complex deposits.
  2. Mine-scale numerical methods (FLAC & FEA) for stability analysis of mine structures, partings, and barriers.
  3. Seismic monitoring of mine structures in coal and non-coal mines.
  4. Hard roof management in coal and non-coal mines.
  5. Real time monitoring of geotechnical parameters for ground safety.
  6. Condition monitoring of machines, equipment and support systems deployed in mines.
  7. Techno-economic evaluation of mining and allied industry projects.
  8. Embedded systems for safety and productivity optimization in coal and non-coal mines.
  9. Scientific investigation of mineral rules, regulation and policy to exploit complex deposits.
  10. Preparation of mining plan and mine closure plan for coal and non-coal mines.
  11. Underground structural health and reliability assessment and management.
  12. Mine life cycle assessment and sustainable mining practices.

Important Achievement:

  1. Application of numerical modelling for simulating the caving behaviour of the overlying rock beds, predicting the caving span, convergence, closure abutment stress and estimation of support resistance. This numerical modeling on prediction of longwall roof behaviour with goaf simulation has greatly helped to overcome strata control problems, so long prevalent in longwall mines of India.
  1. Introduced microseismic monitoring in mines and development of “Specific Instability Criterion” and modules in MATLAB to calculate seismic parameters has helped to quantify the degree of instability over worked out panels and previously extracted unknown workings in coal mines. The microseismic monitoring technique can be effectively used for ground control, roof fall prediction, detection of unknown workings below railway tracks and monitoring of rock burst prone mines.
  1. Hard roof management by induced caving of massive and bridging rock beds by hydro-fracturing with water injection under high pressure and development of methodology for design and planning of hydro-fracturing at any locale. This has potential to improve the cavability and fragmentation of the broken rock debris in the goaf. Mining with hydro-fracturing as caving technique will improve both productivity and safety of the mines.
  1. Introduction of “Oblique shortwall mining method” for fast liquidation of standing pillars in underground coal mines in India. The method was designed and implemented for the first time in India at Balrampur mine, SECL and RK-NT mine, Srirampur Area, SCCL. Extraction was successfully completed in 10 shortwall panels of Balarampur mine, and 4 shortwall panels in RK-NT with this technology.

Section 2: Product, Process & Technology Development

Mandate:

The section is formed to uncover vast potential of different research groups of CSIR-CIMFR to create tangible R&D impact to the mineral and energy industry at large and the society in particular. The aim is to equip Indian mineral and energy industry with quality In-House products, processes and technologies those can compete well with global peers. The section also endeavours to improve societal living conditions by engaging the society, academia and industry as partners and apply smarter approaches to obtain faster results. The section is open to individuals for creating value chain products in order to provide impetus to the initiatives of Government of India, such as – Make in India, Skill India and Swachchh Bharat Sashakt Bharat, etc.
