Electric locomotives are the main vehicle meant for nonproduction material and people transportation at colliery horizontal haulage drift. They transport 94% of the whole freight turnover. The battery locomotives became the most widely spread in mines. The distance of freight and people transportation is up to 5-10 km. The productivity isn’t practically limited and is not regulated by the number of locomotives working [1].
That’s why the prime importance is attached to the further technology improvement and locomotive haulage development.
According to MakNII report in the period from the year 2001 till the year 2005 in Ukrainian coal industry 43 accidents took place during the locomotive haulage work on shaft transport. That indicates the necessity of caring out works aimed at the increasing the labor safety on shaft locomotive transport. The increase of labor safety is possible in terms of introduction into project engineering and transport cutting-edge science and technology inventions exploitation.
The goal of the work is the development of surveillance system of the shaft battery locomotive AM8D and substantiation of its characteristics.
The goal achievement requires the solving of following objectives:
In the MPhil Video surveillance system of the shaft battery locomotive AM8D is introduced. It enables to improve the better view from the operator’s cabin and to reduce the injury rate during operation of the locomotive transport in Ukrainian coal mines.
Debely V.L., Debely L.L., Arshava V.G., Morozov I.F., Yakovlev V.S., Samorodov A.I., Tchuiko I.T., Goltsov A.N., Ravdonis V.A., Bunko V.A., Volotkovsky S.A., Piavniak G.G., are the scientists to work at the problems of safety increase during the operation of shaft locomotive transport, and identification of locomotive haulage traumatism causes.
According to MakNII report up today there exist high level traumatism problem on the locomotive transport. There observed an annual quantitative increase of fatal injury rate accidents. That’s why the means development of safety increase in Ukrainian coal mines on shaft locomotive transport is considered to be up to date.
According to MakNII in the period from the year 2001 till the year 2005 in Ukrainian coal industry 43 accidents took place during the locomotive haulage work on shaft transport.
The patterns of fatal injury rate are given bellow:
The analysis given above has shown that nearly 50% of locomotive operation lethal traumatism accidents were caused by poor vision from the operators cabin. That’s why locomotive running-down accidents, pressure to sample units (lining, pipelines), locomotive operators injury rate while operating the locomotive in the cabin in the standing position as well as looking out on the move take place. For safety increase of such mode of transport it is suggested to equip electric locomotive with a video surveillance system.
To stave off locomotive transport injury rate in haulages with distances not meeting safety requirements it is suggested to use Stationary Video surveillance system of the shaft battery locomotive AM8D, which is equipped with video camera fastened to locomotive.
Stationary Video surveillance system of the shaft battery locomotive consists of video camera video monitor and cables.
The selection of video camera was made according to the following requirements: explosion safety, dust and moisture containment, corrosion withstandability , resolving capacity, response level; small weight and clearance. Under analysis of sources [2,3,4] the video camera TTC-281Åõ was selected. (see table 1.)

For video signal transmission from video camera to monitor the cable RK-75-2-11 can be used. Supply of Stationary Video surveillance system is carried out by accumulator locomotive battery. Any flexible cable, meant for 12V voltage (video camera) and 24V (video monitor) permitted to bring up into operation in coal mines (cables are not shown in Picture 1).
Video camera (item 1. See Pict. 1) is installed on locomotive carcass above buffer device, where metal angle piece is welded on, to which video camera blacket is fastened by means of bolted connection. Video monitor is in the operator’s cabin to the left of operator. For fastening a welded construction consisting of 2 channel bars and metal plate, bolted connections. To protect the monitor the construction back panel is equipped with metal sheet containing aperture for cable plug-in as well as removable metal visor used to preserve from objects falling from above. Monitor plug in is carried out by means of in-cut connections.
