In this paper the authors discuss the technical feasibility of oblique shortwall mining of developed pillars for 63L shortwall panel of Balarampur Mines, South Eastern Coalfields Ltd. Different numerical models were studied to assess the cavability of the overlying strata of the Passang seam over developed bord and pillar workings and predictions are made of strata …
Many operations now utilise a system that includes the regular reporting, inspection and remediation tracking for identified defective strata support in outbye areas of the mines (e.g. Fig. 8). These strata defects are also tracked in global information system (GIS) enabled maps so that the defects may be identified prior to planning tasks to ...

Abstract: With the ever-moving challenge to increase safety and productivity in mines, the ability to understand what your strata is doing in 'real-time' is incredibly important. New technologies …
However, as mining progresses, particularly for strip mining operations, a body of knowledge is acquired which reduces this uncertainty and can potentially be used by mining engineers to improve the prediction of future mining conditions. In this paper, we describe a new method to support this approach based on modelling and neural networks.
Keywords: monitoring, ground support, rockbolt, digitalisation, strata control, automation 1 Introduction Strata support in an underground excavation is a primary concern for miners. Geotechnical engineers choose the optimal ground support scheme based on the rock mass properties, design guidelines and their experiences.

In recent years, many scholars had established the breaking model of the roof strata in the longwall mining panel face and studied the relation between the shield and roof strata in the longwall ...
Strata control is a critical aspect of mining operations in South Africa, a country rich in mineral resources ... High temperatures, increased pressure, and more complex geological formations are factors that demand advanced strata control techniques. Support systems like rock bolts, mesh, shotcrete, and hydraulic props are employed to ...
The Longwall Top Coal Caving (LTCC) method has greatly improved the production of ultra-thick underground coal resources. However, face fall and support closure have been becoming highly frequent accidents at the working face, and seriously threaten the safety of miners. The key to avoiding these problems is to reveal the structural evolution of the roof strata and then choose …
It is highly flawed to forecast the support requirement without reasonable assessment of caving behaviour of strata in a given geo-mining condition. This paper reviews the salient points related to the strata technicalities, support resistance and various other aspects related to this subject and the state-of-art of the existing approaches.
