FIELD: junction support between mine workings. SUBSTANCE: junction support has front and rear units whose bases and roofings are connected by tongue-and-groove joints. Hung from sides of extreme units on roofings by means of tongue-and-groove guides are side guards for displacement along roofings. Provided on front ends of front units are box-type canopies accommodating extensible cantilevers with rams, and provided on rear ends are hinged additional cantilevers whose motion downward is limited by stops. EFFECT: higher efficiency. 4 dwg
