A new nugulanid genus from the gallovian of kutgh (Gujarat), india
(1973) S. Kanjilal; G.S.P. Singh
The new nuculanid genus Rcticulana n.gen., typified by R. calloviensis n.gen. and n.sp.j is characterized by its reticulate ornamentation. No Jurassic form with such an ornamentation is known so far. © 1973 Oxford University Press.
Assessment of support capacity requirement for longwall working under difficult caving strata conditions
(International Society for Rock Mechanics, 2009) G.S.P. Singh; U.K. Singh
Reliable assessment of caving behavior of strata and support capacity requirement has been an issue of great demand for reducing the strata control risk while planning of longwall workings specially in difficult to cave strata conditions. This paper describes the findings of an integrated modeling approach for assessment of roof cavability and estimation of optimal support capacity for longwall workings in a given geo-mining condition. A numerical modeling approach is described for assessing the progressive caving behavior of strata and performance of a hydraulic powered roof support in a given geo-mining and strata condition. The modeling approach for support selection is suggested for regular as well as en masse caving conditions integrating the results of numerical modeling and field observation of 23 longwall panels worked in different coalfields of India. A mathematical approach is used to assess the effect of dynamic loading due to en masse caving and to estimate the design requirement of rapid yield valve. The modeling results of a case study of Churcha mine, a mining site well known for its difficult caving strata characteristics in Sonhat coalfield of India is also described. © ISRM International Symposium on Rock Mechanics, SINOROCK 2009.
Stabilization of Mine Waste Dumps Through Bio-Engineering
(Springer, 2024) Anupam Chaturvedi; G.S.P. Singh; Sanjay K. Sharma
A continual increase in the quantity of wastes produced make stabilization of waste dumps a formidable task both from economic and technological standpoints. Of late, bio-engineering approach has been emerging as one of the most, affordable, eco-friendly, efficient and widely used methods of stabilizing such waste dumps. This study enumerates various plant species that can be used to reinforce coal mine waste dumps, the factors that affect the choice, and the techniques used to measure their effectiveness as a bio-engineering tool. The outcome of this work can be used for the selection of suitable plant species that would ensure long-term maintenance of the ecosystem as well as mechanical stability of the dumps. Locally available native species that are likely to blend in with the surroundings and adapt quickly to the climate have been suggested for the vegetation of sterile dumps. The Miyawaki plantation approach is recommended as it promotes higher survival, aids in ecological restoration, and improves the mechanical stability of the dump slope. © The Institution of Engineers (India) 2023.
