Abstract: Because the road surfaces of the underground roadways in coal mines are slippery, uneven, with dust and water mist, and the noise and light illumination The government defines the eco-environment protection area as a visual range of important traffic trunks, rivers, and lakes. In the non-mining area, the Eco-environmental assessment model of the mining area in

The results show that, with the exception of the Bayan Obo mine, the support index was greater than the pressure index in terms of mining and human activities in all mining areas.Many mines have introduced the tunnel boring machine (TBM) to improve the efficiency of rock tunneling because of its high propulsion capacity, safe working space, and intelligent equipment. In contrast, the operating environment of coal mines is often under complex geological conditions such as high ground stress, large depth of burial, high Adaptive Modification of TBM Tunneling in Coal Mine

See Reference 4. g To estimate Coal remains a very important source of energy for the global economy. Surface and underground coal mining are the two major methods of coal extraction, and both have benefits and drawbacks. Surface coal mining can have a variety of environmental impacts including ecosystem losses, landscape alteration, soil destruction, and changes An Overview of Soil Pollution and Remediation Strategies in Coal Mining

Coal is the most prevalent energy source in China and plays an important role in ensuring energy security. The continuous monitoring of coal mining activities is helpful to clarify the incremental space of coal production and establish a rational framework for future coal production capacity. In this study, a multi-source remote sensing approach Combined with the geological conditions of the 150802 roadway in Liuzhuang Coal Mine, the distribution law of the tensile stress of the roof support end in the unsupported roof area under(PDF) Application and Development of Smart Mine in China

This subpart applies to surface mobile equipment at surface coal mines and surface work areas of underground coal mines. The purpose of this safety program is to promote and support a positive safety culture and improve miners' safety at the mine. § 77.2101. Definitions.It is widely used in coal mine underground equipment positioning and information transmission. In view of the above problems, this research uses the WLR-5A mining unmanned wheeled chassis experimental platform; uses two UWB receivers to infer the position and yaw information of the vehicle in the underground roadway through the Research on Location Estimation for Coal Tunnel Vehicle

Mining developments in alpine coal mining areas result in slow or rapid ground subsidence, which can lead to melting and collapse of permafrost. This paper integrated unmanned aerial vehicle (UAV) images and satellite-based SAR interferometry images to monitor intensive surface mining subsidence during reclamation. Digital Ecological damage in mining areas largely affects the regional ecological environment and ecological security. In China, ecological restoration in mining areas is urgent, as its environmental protection lags Ecological Management and Land Rehabilitation

Coal mining can cause groundwater pollution, and microorganism may reflect/affect its hydrochemical characteristics, yet little is known about the microorganism’s distribution characteristics and its influence on the formation and evolution of mine water quality in underground coal mines. Here, we investigated the hydrochemical Underground Mining equipment list. Soft rock mines, such as coal, do not require the use of explosives for extraction. These rocks can be cut with the mining tools provided by modern technology. Soft rocks are also salt, potash, and bauxite. In hard rock mines, extraction is carried out by drilling and blasting.MINING Equipment List Mining Tools Names

Understanding the synergistic effect between topography and vegetation in the underground coal mine is of great significance for the ecological restoration and sustainable development of mining areas. This paper took advantage of unmanned aerial vehicle (UAV) remote sensing to obtain high-precision topographic factors (i.e., digital Previously conducted studies have established that soil contamination by trace elements (TEs) around coal mines affects ecological biodiversity and human health. One of the ways to protect the health of the surrounding population of coal mine sites is through the assessment of contamination impacts by accurate procedures for the Minerals Free Full-Text Applied Methodological Approach

Excessive exploitation and massive coal mine closures have brought about extensive goafs in Shanxi where 8780 coal mines have been abandoned in the last 20 years. Acid mine drainage (AMD) poses severe environmental impact and has become a prominent problem in Shanxi abandoned coal mine areas, which has aggravated the Over the past decade, unmanned aerial vehicles (UAVs) have been used in the mining industry for various applications from mineral exploration to mine reclamation. This study aims to review academic papers on the applications of UAVs in mining by classifying the mining process into three phases: exploration, exploitation, and Applications of Unmanned Aerial Vehicles in Mining from
