On the slope of the dead end paths are traceed outside the career field. The difference in the marks of dead ends is usually accepted equal to the height of the ledge. The adjacent of the loading tracks from the horizons to the main rollbacks is made on posts during deadlocks.
Road transport is an economical mode of transport for:
1) short and medium performance quarries; 2) in the development of deposits with layers of low power with rapid expulsion of the front of work; 3) for quarries with a complex surface relief and a complex occurrence of minerals, which does not allow laying routes according to the conditions of the plan and longitudinal profile.
Road transport provides greater maneuverability when working in the slaves and dumps, especially affecting that these points do not need to install rail tracks with their frequent and laborious mobility. At the same time, the work of transport and loading mechanisms in the face is greatly simplified, and the conditions of rampant formation are also simplified, in addition, the slaves are greatly facilitated to finalize excavator hires.
The disadvantages of road transport are:
1) the need to use expensive types of fuel (gasoline, diesel fuel) and significant energy consumption per 1 TKM of transportation due to increased resistance to career roads; The main specific resistance to the movement along the rail tracks of the wide track is 2-2.5 kg/t, the narrow track is 4-6 kg/t, on the road in a quarry from 50 to 200 kg/t; In this regard, it is also necessary to note a significant wear of auto -openers, the wear of the car covers in stone quarries occurs 2 times faster than on ordinary roads;
2) a large number of workers necessary for servicing a park of cars and career roads.
The construction program The estimate of the RU helps in the work of enterprises and promotes effective and competent compilation and verification of estimated documentation. Today the program of the RU estimate can be purchased on favorable terms.
