By Józef Paździora (Eds.)

The escalating around the world call for for strength has had the impact, between different issues, of marketing the improvement of coal mining. In a few international locations expert layout workplaces have been organize and scholars informed as experts in mine layout and building. Poland, a rustic having mining traditions stretching over many centuries, is an effective instance, and has won a spot within the vanguard, not just as a coal manufacturer and exporter, but additionally as an originator and exporter of technical mining information. the writer of this publication has himself had 25 years of useful event in mine layout, within the supervision of mining funding implementation either at domestic and overseas, and in addition in directing the actions of the executive Mine layout and experiences place of work in Poland, plus greater than two decades' instructing event within the education of mining engineers, specifically as head of the Mine layout division of the Mining school on the Silesian Polytechnic college in Gliwice. This immense wealth of expertise has caused him to write down the current booklet which discusses the elemental difficulties met with within the layout of underground hard-coal mines

Design of Underground Hard-Coal Mines

The escalating around the globe call for for strength has had the impact, between different issues, of selling the advance of coal mining. In a few nations expert layout workplaces have been manage and scholars knowledgeable as experts in mine layout and building. Poland, a rustic having mining traditions stretching over many centuries, is an efficient instance, and has received a spot within the leading edge, not just as a coal manufacturer and exporter, but in addition as an originator and exporter of technical mining information.

G. the layout at the mine surface or location of machines and equipment in a fixed space). Three-dimensional models are built up using block shapes (scaled down 32 GENERAL PRINCIPLES OF MINE DESIGN Ch. 3 models of the individual facilities) and are used for designing (or visualizing) the spatial layout of the components of the given system and of complete systems. g. ) — for visual illustration (in complicated geological conditions) of seam location in the deposit and deposit disturbances and for planning of mining operations — for visual illustration of certain design conceptions relating to development of the mine surface, the underground sector, individual mine facilities or installations.

Hence the coal preparation plant should be equipped with suitable hoppers for raw and dressed coal. These hoppers are the element equalizing the production capacities of production shafts, coal preparation plant, coal loading facilities, etc. Similarly, throughput capacities of the main gotten transport and winding facilities must be coordinated and inequalities compensated for. Surge bunkers should be located at the shaft top, as always practised in the newly constructed and reconstructed mines.

Group of seams developed by cross-cuts. GENERAL PRINCIPLES OF MINE DESIGN 44 Ch. 3 When the mine model envisages development drivage in the rock (stone drivage), the deposit is cut away from the main shafts. The main heading is driven parallel to the line of strike and perpendicular cross-cuts open up the seam or seams in the form of consecutive panels (Fig. 9). Alternately, the seams are opened using panel drifts. These inclined drifts are driven from the main heading or from short cross-cuts and are used for opening up new sections of the seams of small slope (Fig.
