DEVELOPING METHOD OF HEAVY ABRUPT LAYER WITH CAST SOLID STOWING

摘要

FIELD: mining engineering. ^ SUBSTANCE: invention relates to mining industry and can be used at underground operation heavy abrupt layer with stowing of open area. Method includes implementation of layerwise drifts, upraise and alternate development of cut in horizontal fibers by means of combine and following filling of cuts by cast solid stowing. Before stowing supplying, on cut soil there are laid chutes and are installed shields for reservation as operating layerwise drift in waste horizontal fibers. Layerwise drifts are implemented up to beginning of layer development nearby top or nearby layer soil and they are used for coal transportation, ventilation and feeding of cast solid stowing into cuts of underlying horizontal layer. ^ EFFECT: increase of labour productivity and safety of mining. ^ 8 dwg
