A method for improving transportation lane

Abstract

The invention belongs to the technical field of transport connected roadways, in particular to a transport connected roadway improvement method. A transport connected roadway comprises a rock concentrated roadway and a rock rail roadway, wherein a tunneling stone gate is arranged on the rock concentrated roadway, and the transport connected roadway is arranged between the rock concentrated roadwayand the rock rail roadway; one end of the transport connected roadway is communicated with the tunneling stone gate. The tunneling transport connected roadway design of a working face is optimized, the transport connected roadway and the tunneling stone gate are designed on a straight line, a door poking position of the tunneling stone gate is designed to be a four-way door, the transport connected roadway is directly communicated with the concentrated roadway, the engineering quantity of the rock roadway is reduced, the roadway driving cost is reduced, the requirements of a mine for double effects, mechanization, automation, informatization, intelligentialization, level reduction, mining area reduction and staff reduction are met, the design concept of level, straight and simple roadwaydesign is fulfilled, the aim of achieving service and production in one step is achieved, the method is suitable for system optimization of newly prepared mining areas and working faces of the mine, and the method has good popularization value in the aspects of safety, economical efficiency, relieving of exploitation succession tension and the like.

Description

technical field [0001] The invention belongs to the technical field of transportation lanes, and in particular relates to a method for improving transportation lanes. Background technique [0002] The continuous mining operation of underground mines will break the original stress balance, and there will be obvious mine pressure phenomenon in the roadway in the mining area of ​​the working face, and it will show a continuous cycle of periodic changes with the advancement of the working face. The support and maintenance of the roadway often need to be continuously optimized and adjusted according to the actual production, and the stability of the roadway is tested through the mining practice. Generally speaking, after the roadway is excavated, the rock mass around the roadway will be in a state of equilibrium and the stress will be redistributed. , thus causing the deformation of the surrounding rock of the roadway. If this deformation cannot be effectively controlled, the roa...

Problems solved by technology

[0004] 1. The construction and transportation alleyway of the machine lane, Shihmen, and Ⅱ883 return coal to the mountain. The total project volume is large, and there are many coal transportation links. There may be many factors affecting production, which does not conform to the flat, straight and simple integrated design concept

[0005] 2. The engineering volume of the rock roadway in the original design plan is relatively large, which to a certain extent is time-consuming and labor-intensive and increases the mining cost, which does not meet the mine's production requirements of focusing on double effects, four modernizations and three reductions
