FIELD: mining.
SUBSTANCE: face equipment for working in solid working system at underground coal deposit working by bottomhole conveyor that can displace along cleaner and assemblies of shield support secured thereat at the angle. Note here that to define absolute elevation of preset bottom-hole equipment elements (12, 15, 31) along the breakage front (10) a fluid filled hose level (17) is laid. The latter is connected top accurately defined elevation point located at one of parallel excavation entries (13, 14) of basic station (19). Note here that pressure gages (22) are interconnected and connected with central data processing unit with distribution over the length of face equipment at separated elements (12, 15, 31) to hose duct (18, 23, 24) of hose level (17).
EFFECT: accurate definition of elevation mark.
