FIELD: mining industry. SUBSTANCE: complex primarily relates to extraction of seam deposits of coal, manganese and potassium ores. Complex has support sections which are connected with conveyor frame for possible transmission to conveyor frame of torque around column axis and also at loss of side stability, and also for transmission to conveyor frame of torque around axis of longwall proportional to overturning moment from mass of section at loss of section stability in direction of advance in operation on seam deepening. Conveyor sections are rigidly interconnected in direction of limiting movement of each section with respect of adjacent sections around axis which is parallel to axis of extracting column and around axis which is parallel to longwall axis proportionally to actual hypsometry of seam and proportionally to values of moments from weight of support sections at loss of stability at actual seam lying angles. Conveyor is provided with abrasion-resistant transporting member in the form of rubber-rope belt with spread roller-type drive for lower idle line. Also provided are metal side limiters for upper line of conveyor belt. Conveyor is provided with rope extended over its length and connected with follow-up rollers of rectilinear movement of advancing frame. Cutter-loader combine included in universal complex can be operated in coal and hard ore minerals due to employment of dynamic roller-type bits containing small number of replaceable planetary moving cutters. Combine ensures loading of coal or ore to large-height conveyor due to leaving chamfer in cut-face breast by breaking drum with part of its surface being of taper configuration. Drift equipment is made in the form of manipulator having self-propelled carriage and arm with elbow joint in plan between forearm and shoulder and hand provided with grip used for installing and dismantling of posts in drift support, and also of support sections included in set of drift equipment of universal extraction complex. EFFECT: higher efficiency. 18 cl, 8 dwg
