In-time supporting method for roadway fully-mechanized excavating operation

Abstract

The invention discloses an in-time supporting method for roadway fully-mechanized excavating operation, and the in-time supporting method is used for solving the problems of ineffective limitation and prevention on wall rock degeneration damage and low working efficiency of the conventional roadway excavating operation. The method comprises steps of temporarily supporting a fresh roof of a roadway fully-mechanized excavating face under the cooperation of a fully-mechanized excavating machine, utilizing a roadway excavating staggered supporting device to assist the permanent supporting operation of a roadway, and conveying coals which are cut off by the fully-mechanized excavating machine through utilizing a bridge type belt reversed loader and a belt conveyor. The method is reasonable in technological design, stable in supporting and moving, and safe and reliable; a small-circulation and frequent operation type switching mode of the original excavating operation is changed into a long-distance and large-circulation mode, the preparation time wasted by switching different processes is reduced, and the cooperation requirements of the roadway supporting and the fully-mechanized excavating machine are satisfied, so that the temporary supporting of the fresh roof of the roadway fully-mechanized excavating face and the permanent supporting of the roadway are mechanically realized in time; and the supporting quality and excavating efficiency of the roadway are obviously increased.

Description

technical field [0001] The invention relates to a support method for underground roadway excavation operations, in particular to a method for temporary support and permanent support on site by using a roadway excavation staggered support device and a fully mechanized excavator (abbreviation for comprehensive mechanized roadheader) to work together. The timely support method for fully mechanized excavation of the roadway is mainly used for the timely mechanized support of the fully mechanized excavation face of the underground roadway, the newly exposed roof, the net laying of the two sides and the bolting of the roadheader during the excavation operation. Safeguarding operations provide effective security guarantees. The invention belongs to the technological field of roadway excavation support. Background technique [0002] In the current mining, especially in the underground mining of coal mines, the tunneling operation of the underground roadway is a prerequisite for all...
