The characteristics and origin of cleat in coal of Western North China are discussed with respect to field investigation and laboratory experiments. Cleat in coal of Western North China can be divided into two classes: face cleat and butt cleat. Three network patterns of face and butt cleats are identified: reticular, isolated, and random.
Mexico is the world's second-largest producer of mercury after China, churning out some 200 tonnes of the toxic material annually. Photo: UNEP/Jack Hewson. In response, the Mexican government has launched a project to help 19 communities in the Sierra Gorda transition to alternate, mercury-free livelihoods.
Coal development in Mexico is concentrated in the northern state of Coahuila, which accounts for 99% of national production.Mexico produced just over 11 million short tons of coal in 2019, ranking 23rd globally. The U.S. Geological Survey (USGS) reports that Mexico produced 11.9 Mt of coal …

The geological sequestration of CO 2 in coal seams holds significant implications for coalbed methane development and greenhouse gas mitigation. This paper examines the principles, influencing factors, and evaluation methods for geological CO 2 sequestration in coal seams by analyzing relevant domestic and international findings. …
When the carbon capture and storage (CCS) project and coal mining engineering activity occur in the same location, coal mining may also induce wellbore failure if the stope border is too close to the well. This is a real and challenging problem for CO 2 geological storage in the Ordos Basin in China. We consequently investigated …

Salas worked on the volume until his death, with much valuable help from Ing. Hugo Cortez Guzmán. The result is a valuable English-language synthesis of the information available to Salas in the early to mid-1980s about the geothermal, coal, and metal-mining sectors (and some non-metallic resources) of the economic geology of Mexico.
The country's mineral sector accounted for 5.4% of the total GDP. in 2017, as reported by cámara Minera de México, the mining and processing of "metallic minerals" accounted …

'Coal' and 'China' to some extent have become synonymous. China is by far the largest user of coal in the world. In 2016, coal production in China amounted to 3.21 billion tons, about half of the total global coal production. Coal consumption accounts for more than 65% of primary energy consumption in China. The Chinese coal industry greatly …

Most of New Mexico's mineral production comes from coal, copper, and potash. Other …
Coal seam that is thinner than a certain value is defined as thin coal seams (TCS). It commonly occurs in China as it covers 84.2% of the mining area. This situation is even severe in China's large surface coal mines, in which TCS accounts for 10–50% of the total reserve. Most TCS cannot be feasibly mined due to the working conditions of …
