tunnels and underground excavations tunnels and underground excavations tunneling techniques: tunnels are generally grouped in four broad categories, depending on the material through which they pass: soft ground, consisting of soil and very weak rock; hard rock; soft rock, such as shale, chalk, and friable sandstone; and subaqueous. while these four broad types of ground condition require all the heat generated by an underground power cable must be dissipated through the soil. this is quantified by the soil thermal resistivity which can vary from to -cmw. electrical engineers understand the performance of the cable quite well, but to most, the soil behavior is a mystery, usually handled by
the mining process is used to separate rock or ore from surrounding rock. there are four main mining methods: underground, open surface placer, and in-situ mining.the method used depends on the type of mineral resource that is mined, its location beneath the surface, and whether the resource is worth enough money to justify extracting it.aug 02, 2020 kristin piljay getty images. the clay clasts or particles in shale are less than 0.004 millimeters in diameter, so the structure of the rock only becomes visible under magnification. the clay comes from decomposition of feldspar.shale consists of at least percent clay, with varying amounts of quartz, feldspar, carbonates, iron oxides, and organic matter.

coal dust explosions in underground coal mines are pre vented by a generous application of rock dust If an explosion should occur, the rock dust disperses, mixes with the coal dust and prevents ame propagation by acting as a thermal inhibitor or heat sink. To investigate this process in more detail, a number of exthe economic analysis of the use of explosives is an important part of blasting operations in mining and construction. explosives are energy, and the efficient use of this energy is a major factor in keeping rock blasting costs under control. high-energy explosives enhance fragmentation, which ultimately produces a positive effect on production
