摘要:The disintegration of rocks by weathering plays an important role in the occurrence of Acid Mine Drainage (AMD), which is the environmental problem caused by the exposure of sulfide minerals to water and oxygen. The weathering of rocks is, generally, classified into physical or c...

摘要:Underground facilities play an important role in infrastructure of modern society, especially some lifeline engineering, such as subway and railway tunnels, civil air-defense engineering and so on. As we know, the entire cognitive processes of seismic response of underground open...

摘要:Abstract(#br)Goaf-side entry driving in underground coal mines could greatly improve coal recovery rates. However, it becomes more difficult to maintain stability, especially in deep coal mines. Pillar width plays a pivotal role in the stability of goaf-side entry driving. To obt...

摘要:The application of a rock bolting system for Indonesian underground coal mines has been attempted for several years without any success. Recently, two new underground mining trials were conducted in East Kalimantan, Indonesia, in order to investigate the possibility of using rock...

摘要:Over the years, a number of empirical attenuation equations (AEs) have been proposed. However, many established AEs are not accurate enough and sometimes they are confusing to use, particularly when the parameter associated with blasting and geological condition changes. Nowadays...

摘要:In underground coal mines, floor heave is a major problem that is caused by groundwater, high strata stress and weak floors. Controlling the stability of the roadways is the key to maintaining the safety and efficiency of underground mining. Appropriate cement grouting is an...

摘要:A large amount of waste is produced at coal preparation plants. The properties of the waste vary depending on the mineralogical content of the mother rock in which the coal is embedded. The quality of the waste depends on the method of mining and cleaning, but it consists mostly ...

摘要:The waste dump of sulphide-containing rocks is one of the potential acid mine drainage sources, since it contains a huge amount of readily oxidised sulphide mineral, due to its exposure to air and water. The application of the dry cover system is regarded as one of the best pract...
