Abstract: Effective mining horizon sensing is an issue of major importance in the coal mining industry because it directly impacts the productivity and safety of the resource recovery process. However the development of automated mining horizon control capability has been significantly hindered by a fundamental lack of sensing that can reliably measure the coal-strata geological structure in ...

The factor most affected by coal mining was GWT, which dropped from a depth of 35.41 m before mining to a depth of 43.38 m after mining at the Bulianta Coal Mine based on water well measurements. Ground-penetrating radar at frequencies of 25 and 50 MHz revealed that the deepest GWT was at about 43.4 m.

Finally, as an example, the characteristics of ground penetrating radar images are analyzed based on the detection results of No.015 water proof gate of Nanye coal mine.

gobs of four coal seams, and the caved zone of lower coal seam develops to fine sandstone of the 5 # coal seam floor. The ground penetrating radar has shown much promise i n the detection of overlying strata movement.

The coal mining horizon is the horizontal path the machinery follows through the undulating coal seam during the mining operation. A typical mining practice is to leave a thin remnant of coal unmined in order to maintain geological stability of the cutting face. If the remnant layer is too thick, resources are wasted as the unmined coal is ...

The aquifers surrounding the coal mine become drained, which leads to a sinking of the depression cone. This sinking alters the natural hydrological conditions underground by creating paths of lowered resistance. What this then leads to is water penetrating the open pit and underground workings.

for improved safety through reduction in personnel in the most hazardous coal cutting areas. In situ, real-time coal seam measurements using the Special Technologies Laboratory (STL) ground penetrating radar (GPR) technology were shown feasible by a demonstration in a Utah coal mine on April 21, 1994.

The application of ground penetrating radar (GPR) has been of great interest in the exploration and mining industry, especially with regards to subsurface mapping. After the rapid commercialisation of GPR in radar antennas, analytical software has extended its application as an exploration method in ple archaeological sites.

1. Introduction. Coal resources play a significant role in daily life and industrial production .Mining activities affect the original state of stress in the coal rock formations, leading to change of coal seam stress state and ultimately fracture and deformation of internal structure, .Resultantly rapid instability of coal mass may occur, culminating in the phenomenon of coal rock dynamic ...

Use of ground penetrating radar in underground coal mining. This paper reports on a novel application of ground penetrating radar to a longwall steering problem in the coal mining industry The main goal of the work was to determine whether a radar-based . us mining gpr equipmentpanies.

First penetrating the region in 1872, the railroad quickly came to dominate the Indian Territory coal industry. The Katy became part of a complex web of railroads controlled by Jay Gould. In the mid-1870s, McAlester sold his Oklahoma Mining Company to the Osage Coal and Mining Company, a larger concern that he and several partners had founded.

Ground penetrating radar is used in salt mining applications to maximize yield. GSSI GPR allows miners to navigate continuous mining machines by way of imagining the salt/shale interface. In addition, GPR can be used to maintain proper roof structure to create a safe mining environment, while at the same time maximizing the yield.get price

ground penetrating radar (GPR) performs in characterizing near surface coal mine related features. Coal mining in the Eocene – Paleocene Wilcox Formation (Fisher, 1963) was carried out at Malakoff (near Dallas), Texas and Bastrop (near Austin), Texas in the first half of the 20th century: generally during the period from 1905 to 1940.

45 years of coal mining leadership Mining Energy 45 years of coal mining leadership experience and data to evaluate LNG use, while reducing operating costs and emissions. Should the LNG and diesel hybrid fuel be expanded across Teck''s steelmaking coal operations, there is the potential to eliminate approximately 35,000 tonnes of carbon dioxide emissions annually and reduce fuel costs by
