FIELD: mining.SUBSTANCE: invention relates to mechanized support used with downhole equipment for working in continuous development system. Proposed is face equipment for mechanical production in continuous development system, primarily in underground coal mines with face conveyer (17) located along front of works in bottom, with possibility of movement along face conveyor (17) by production mechanism (18) and frame (10) of shield support secured at angle to face conveyor (17). At that, for determination of height of opening of bottom-hole space in area of face conveyor (17) on separate frames (10) of shield support between downhole conveyor (17) and at least one basic component of frame (10) of movable shield is laid hose level (21) with hose filled with fluid (22), and at least on one end of hose (22) there is pressure sensor (23, 24). At that, in addition to account of longitudinal and/or transverse inclination of face conveyor (17) and basic component of frame (10) of movable shield when determining height of face on bottom-hole conveyor (17) and having end hose level basic component of frame (10) of shield support there is at least in two axes of rotation relative to horizontal device (25, 26) for measuring inclination. At that, pressure sensor (23, 24) and inclination measuring device (25, 26) are connected with data processing and control device.EFFECT: simplified determination of height of opening of bottom-hole space.21 cl, 6 dwg |
