METHOD OF CONTROL OF COAL MINING COMPLEX AND DEVICE FOR ITS EMBODIMENT (VERSIONS) Russian patent published in 1999 - IPC

Abstract RU 2131976 C1

FIELD: mining; applicable in underground mining of coal with use of coal shearer and hydraulic-powered support. SUBSTANCE: method of control of coal mining complex, which consists of coal shearer and powered support unit with local control panel is realized by operator moving in car near and in synchronism with shearer advance at a distance of stretched hand. Control of coal band in roof and floor is accomplished from car by the same operator with periodic taking of coal samples from roof and floor by car mechanism powered hydraulically from support hydraulic panels or from shearer. Control device of operator's car, car guides and car motor. Car and guides are located on complex framework before support face props. Guides are made in the form of two pipes with bottom recesses and circular chain inside pipes engageable with car lugs. Car internal space is airtight and enclosed in transparent dome with small window for operator's hand. Car has manipulator with hydraulically operated spoon for taking samples, fan with dust suppressor, gun for connection of hydraulic power source. Car motor has constant telescopic communication with shearer and its advance is not less than one advance step of support. Accommodated inside telescopic communication appliance are hydraulic line and electric wires for supply of manipulator and car fan. Invention provides for presence of man in zone of shearer and support and observance of sanitary norms and regulations with respect to dust content in ambient atmosphere and comfortable operating conditions for operator. EFFECT: higher efficiency. 4 cl, 1 dwg
