274 coal fields and mining districts in NM ~30 districts have had zero production Each district is classified by predominant commodity Each district can have more than 1 commodity type 28 coal fields 40 industrial minerals districts 173 metals districts 32 uranium districts Chino copper mine San Juan coal mine
Detecting surface coal mining areas (SCMAs) using remote sensing data in a timely and an accurate manner is necessary for coal …
Although the coal industry of Mexico is relatively small with 15 million tonnes of coal mined per year, the coal mines of northern Mexico are notoriously gassy and these three …
We used the object-oriented decision tree method (Zeng et al. 2017) to extract the SCMAs in Xilingol for the years of 1990, 1995, 2000, 2005, 2010, and 2015.
The DCNN using seismogram images as the inputs reached the best performance with more than 94% accuracy. As mining is a dynamic progress which could change the characteristics of seismic signals, the temporal variance in the prediction performance of DCNN was also investigated to assess the reliability of this classifier during mining.
With a list of known coal mine locations from various countries, a training dataset of "Coal Mine" and "No Coal Mine" image patches is prepared using Sentinel-2 satellite images with 13 ...
The classification of rock from coal on rib images has been studied with machine learning techniques to assist for the automated rib stability analysis and enables the shearer to adjust the drums without human intervention. Classification of rock and coal is one preliminary problem for fully automated or intelligent mining. It assists for the …
Methods by which coal can be studied and classified are described, including coal petrography, vitrinite reflection measurement, and chemical and physical characterization methods (ultimate...
By ia T. McLemore, 2017. This Resource Map locates and describes 246 mining areas in New Mexico (excluding coal fields). The included booklet begins with a brief description of the history of mining in New Mexico and is followed by discussions of previous work, mining claims, the definition of a mining district, mining methods, and …

The CMRR system was modified by adding additional parameters, namely, the width of roof span and the density of overburden rock, and roof support requirements were recommended to select the suitable rock bolting system including length and spacing of rock bolt. The coal mine roof rating (CMRR) classification system has been applied …
Fig. 7 (a) is the Heidaigou coal mining area, the initial imagery was collected on Aug. 26, 2017. Fig. 7 (b) is the Saraji coal mining area, the original image was collected on Feb. 1, 2018. Comparing the two images with the original images and the actual data, we can see that the two images make a good distinction between coal area and gangue ...
The coal mine roof rating (CMRR) classification system has been applied in a number of coal mines worldwide including Australia. However, the current system cannot be used directly to design ...
Deep learning is an effective way to improve the classification accuracy of coal images for the machine vision-based coal sorting. However, the related research on deep learning-based mineral ...
Fig. 1 compares the surface state differences of coal and gangue in various situations based on the proposed model. In the ideal laboratory environment, the light intensity is high, the coal and gangue image acquisition process is simple, and the camera receives more light signals, so it is easy to distinguish coal and gangue; however, in the …
