2019-7-12 designing underground mining operations involves a comprehensive process of integration of three-dimensional data through the use of information from exploration, engineering, and extraction processes.
Read MoreThe principal means of access to an underground ore body is a vertical opening called a shaft. The shaft is excavated, or sunk, from the surface downward to a depth somewhat below the deepest planned mining horizon. At regular intervals along the shaft,
Read More2020-8-25 1. Underground Mining Methods 1.1. Classification of Underground Mining Methods Mineral production in which all extracting operations are conducted beneath the ground surface is termed underground mining. Underground mining methods are usually employed when the depth of the deposit and/or the waste to ore ratio (stripping ratio) are
Read More2019-10-7 This paper presents a comprehensive simulation model of underground coal mining processes in a fully mechanized longwall mining face. A number of simulation experiments were performed. The face productivity is estimated as a function of various factors such as the technical parameters of mining machines, face length, gas factor, shearer operation mode, distributed
Read More2019-10-23 This volume deals with economic aspects of mining companies’ development strategies, various mineral deposits development techniques, imitational modeling of mine workings with rock massif, methane extraction technologies during coal mining, geomechanical processes during plow mining, mining transport importance for mineral extraction, massif strain-stress state management using non-explosive destructing materials, and surface mining
Read MoreOnce a mining lease has been awarded to an operator, exploration (i.e. evaluation of the resource) takes place, followed by a planning and development process before excavation or mining begins. The initial task is to gain access to the seam from the surface by some means (shafts, drifts, etc – see Access to Seam from surface section for these terms).
Read MoreThis method is called underground mining, whose types are explained below. Room and Pillar Mining. In this method, mining is carried out in an ore deposit, leaving behind some of the ore in the form of columns to support the roof and prevent it from collapsing. Thus, it results in the formation of spaces called ‘rooms’, where the ore is ...

Read More2021-5-7 Underground mining is carried out when the rocks, minerals, or precious stones are located at a distance far beneath the ground to be extracted with surface mining. To facilitate the minerals to be taken out of the mine, the miners construct underground rooms to work in.

Read More2020-3-12 Below are seven different types of mining processes: 1. Surface mining. There are two main types of mining – every method can be divided into either surface or underground. Logically, surface mining is used to gain access to minerals located closer to the earth’s surface. The place where minerals can be found is often called a seam.

Read MoreCutting Processes. It has been stated that a longwall advances by cutting slices off the block. This is relatively simple for hand worked faces and with a coal plough, but with mechanized longwalls using shearers the means of doing this is not as straightforward as it would at first appear because of the complexity of the equipment.
