Stability Assessment of Stoping Operations in Friable Ore Bodies under an Open Pit Mine using Strength-based Mining Sequence Factor

Sruti Narwal; Debasis Deb; Sreenivasa Rao Islavath; Gopinath Samanta

Articles in Press, Accepted Manuscript, Available Online from 06 December 2024

https://doi.org/10.22044/jme.2024.14872.2828

Abstract
  A novel underground mining method is proposed to extract friable chromite ore bodies in weak and weathered limonitic host rock below an open-pit mine. The conventional underground methods do not instil confidence since GSI (Geological Strength Index) of ore bodies and host rock lies below 35. Series ...  Read More

Application of clustering methods to identify high-grade zones a case study: Lar porphyry deposit, Sistan and Baluchistan province, southeastern Iran

Moslem Jahantigh; Hamidreza Ramazi

Articles in Press, Accepted Manuscript, Available Online from 13 October 2024

https://doi.org/10.22044/jme.2024.14582.2747

Abstract
  Various methods have been used for clustering big data. Pattern recognition methods are suitable methods for clustering these data. Due to the large volume of samples taken in the drilling of mines and their analysis for various elements, this category of geochemical data can be considered big data. ...  Read More

Stability Analysis of set-up Room of a deep Longwall Panel of Lndia using 3D Numerical Modelling Technique

Avula Rajashekar Yadav; Sreenivasa Rao Islavath; Srikanth Katkuri

Volume 15, Issue 4 , October 2024, , Pages 1291-1308

https://doi.org/10.22044/jme.2024.14360.2689

Abstract
  The installation gallery/set-up room of a longwall panel is driven for installation of the longwall face machineries to start the extraction of coal from the longwall panel. The width of the installation gallery is 8 to 9 m. This gallery needs to be stabilized till the face machineries to be deployed ...  Read More

A New Method for Stability Analysis of Chain Pillar in Longwall Mining by using Coulmann Graphical Method

Mohammad Sina Abdollahi; Mehdi Najafi; Alireza Yarahamdi Bafghi; Ramin Rafiee

Volume 15, Issue 4 , October 2024, , Pages 1461-1476

https://doi.org/10.22044/jme.2024.13754.2548

Abstract
  The stability analysis of chain pillars is crucial, especially as coal extraction rates increase, making it essential to reduce the size of these pillars. Therefore, a new method for estimating the load on chain pillars holds significant importance. This research introduces a novel solution for estimating ...  Read More

Determination of the Caving Zone Height using Numerical and Physical Modeling based on the Undercutting Method, Joint Dip, and Spacing

Behnam Alipenhani; Mehran Jalilian; Abbas Majdi; Hassan Bakhshandeh Amnieh; Mohammad Hossein Khosravi

Volume 15, Issue 4 , October 2024, , Pages 1539-1562

https://doi.org/10.22044/jme.2024.13984.2609

Abstract
  The paper presents the effect of the dip of joints, joint spacing, and the undercutting method on the height of the caving in block caving. The obtained results show that among the three investigated parameters, respectively, the dip of joints, undercutting method, and joint spacing have the greatest ...  Read More

Effect of Tunnel Location Related to Inclined Coal Strata on Excavation-Induced Displacements of Mine Tunnel: Application of Calibrated Numerical Model

Morteza Javadi; Ashkan Shahpasand; Shahrbanou Sayadi; Arash Shahpasand

Volume 15, Issue 1 , January 2024, , Pages 203-221

https://doi.org/10.22044/jme.2023.12611.2291

Abstract
  The stratified-sedimentary rock mass, as the typical host ground of coal mine tunnels, is characterized by highly non-isotropic deformation due to the very persistent discontinuity of bedding planes. This study evaluates the effect of tunnel location relative to the host ground strata on the excavation-induced ...  Read More

Investigating Effect of Induced Stresses due to Coal Panel Extraction on Next Panel Strata behavior during Mechanized Longwall Mining: a Case Study

Emad Ansari; Ramin Rafiee; Mohammad Ataei

Volume 15, Issue 1 , January 2024, , Pages 381-399

https://doi.org/10.22044/jme.2023.13787.2560

Abstract
  Due to longwall mining, a large space without any support is created, and the in-situ stress regimes change. The change of the in-situ stress regimes affects the roof and face of the adjacent panel. In other words, the strata behavior would be different from the intact condition during the previous panel ...  Read More
