The invention provides a transportation roadway supporting and transporting integrated system. The transportation roadway supporting and transporting integrated system comprises an anchoring support,advance supports and an end support, wherein the advance supports are connected with a reversed loader transportation groove and a crusher; the anchoring support is arranged between the reversed loader transportation groove and a belt conveyor self-moving tail; a pushing anchoring point of the anchoring support is arranged below a bridge starting section of the reversed loader transportation groove; the advance supports are sliding type supports; a main frame and auxiliary frames advance alternately to achieve overall advancing of the advance supports; a base of the main frame is fixed to thereversed loader transportation groove or the crusher; the crusher is arranged between the first set of advance supports and the second set of advance supports; a drive mechanism of the crusher is obliquely arranged above a crusher body; and the end support is connected with the reversed loader transportation groove through a pushing jack. According to the system, a self-moving mechanism of a reversed loader is omitted, advancing is achieved through power of the advance supports, equipment is simplified, meanwhile, the structure is compact, and the occupied roadway space is smaller.
Description
technical field [0001] The invention relates to the field of fully mechanized mining in coal mines, in particular to an integrated system for transport roadway support and transportation. Background technique [0002] The strengthened support (including end support and advance support) of the transport roadway in fully mechanized mining and fully mechanized caving working faces in coal mines has always been an important link affecting coal safety and efficient mining. The "Coal Mine Safety Regulations" stipulates: Within 20m of the connection between the exit and the roadway, the support must be strengthened; the "Notice of the State Coal Mine Safety Supervision Bureau on Strengthening the Prevention and Control of Rock Burst in Coal Mine" stipulates that mines with rock burst regulations have safe exits from coal mining faces with impact risks. The advance support range at the connection with the roadway shall not be less than 70 meters, and the advance support range at the...
