Although the growth in global coal consumption has been sharply slowed with the falls in China offset to a greater extent by the increasing demand in India and other emerging Asian countries, coal still remains the largest source of energy for the world with a share of almost 30% by 2040 [1]. Mining industry plays an important role in extracting underground resources, including coal [2]. However, a large number of disastrous mine accidents, such as flood, water inrush, tunnel collapse, gas outburst, and gas explosion, have been reported due to water and gas migration caused by the mining activities, posing a threat to the environment and also to the health and safety of field workers [3–5]. According to incomplete statistics, mining-induced accidents kill over thousands of workers around the world every year, especially in developing countries such as China and India. Water inrush and gas explosion accidents are the major causes for the reported mine accidents [6, 7].
Source discrimination of mine water plays an important role in guiding mine water prevention in mine water management. To accurately determine water inrush source from a mine in the Jiaozuo mining area, a Piper trilinear diagram based on hydrochemical experimental data of stratified underground water in the area was utilized to determine typical water samples. Additionally, principal component analysis (PCA) was used for dimensionality reduction of conventional hydrochemical variables, after whi...

Abstract Many Chinese coal mines are highly gassy with abundant coal mine methane occurring in complex geological conditions and emitted as a greenhouse gas into the atmosphere during mining operations. Major accidents due to coal and gas outbursts and gas explosions also frequently occur leading to fatalities and financial losses. Conventional technologies using specialized roadways and extensive short drilling holes are unable to meet the demand of today's high production mines with strict saf...

A trial airborne electromagnetic (AEM) geophysical survey was carried out across a 13 × 9 km area of the northern Nottinghamshire (UK) coalfield. One of the objectives was to examine the influence of coal mines (collieries) and associated spoil heaps situated above the Triassic Sherwood Sandstone aquifer. The conductivity models obtained from the AEM survey revealed extensive zones of enhanced subsurface conductivity in the vicinity of all the collieries in the survey area. The present study pro...

This study is to determine the spatial distribution characteristics of Cu and Zn adsorption on the sediments of the estuary of Dianchi Lake, as well as the composite adsorption law of Cu and Zn on combinations of sediment organic matter, metal oxides, and organic-inorganic composites. The relationship between the adsorption contribution of each component of the substance. A static adsorption experiment was applied to the sediments in the estuary of Dianchi Lake. The relationship between adsorpti...

Slurry flow in mining-induced overburden fractures is an important theoretical concept for the grouting design of longwall overburden grout injection engineering. In this study, a visual experimental simulation system of longwall overburden grouting was designed to study the flow, pressure distribution, consolidation, and fill thickness of fly ash slurry in overburden bedding separation. Experiments showed that the slurry generates a radial and bidirectional flow during nonpressure grouting and ...
