Abstract

The invention relates to a laneway disposing shape of a coal mine, in particular to a laneway disposed by using large U to sleeve small u, which solves the problems of driving along a groove and gas control of a stope in the prior laneway disposing mode. The laneway comprises a stope, a small u-shaped laneway is arranged at the periphery of the stope, the small u-shaped laneway comprises a belt laneway and a return airway which are arranged on both sides of the stope, the front side of the stope is provided with a cutting hole, a large U-shaped laneway is arranged outside the small u-shaped laneway and comprises a head-to-tail connection device, a ventilation laneway, a ventilation connection laneway and a gas tail laneway, wherein the head-to-tail connection device and the ventilation laneway are positioned outside the belt laneway, the ventilation connection laneway is arranged outside the cutting hole, the gas tail laneway is positioned outside the return airway, and a plurality ofentity supporting coal pillars are arranged between the large U-shaped laneway and the small u-shaped laneway. The laneway disposing shape solves the problem of gas control of the stope and increaseswork efficiency.

Description

technical field [0001] The patent of the present invention relates to a roadway arrangement shape of a coal mine, specifically a roadway arranged in the form of a large U set and a small U. Background technique [0002] At present, mining technology is generally adopted in the underground coal mining process of my country's coal mines, and the matching working face roadway layouts include "U" type, "U+L" type, "U+I" type and other roadway layout methods. It can basically meet the production needs under high gas conditions, but under high gas conditions, there are disadvantages that are difficult to overcome in the excavation of the tunnel roadway and the ventilation gas control of the mining face. Contents of the invention [0003] The patent of the present invention provides a roadway arranged in the way of large U and small U in the mining face under high gas conditions in order to solve the problems of tunneling and gas control in the mining face existing in the existing...
