Problems solved by technology

However, when the surrounding environmental conditions transition from ample to narrow and restricted, that is, when there is a transition and conversion between the above two tunnel forms, there is currently no relevant technical solution in China.

Embodiment Construction

[0015] The invention is further described below in accordance with specific embodiments of the present invention.

[0016] A method of excavation of a laminated mine method, wherein the method comprises the step of: a, under the conditions of building environmental conditions, first transition from a horizontal separation mine method to a level Small net distance form, reduce similar two "mouth" hindlets (a tunnel looks into a "mouth" glyph, the same), the horizontal level of the two tunnels is controlled in the viewing rock level 3 ~ 5m; B, then two tunnels pass flat, longitudinal line-shaped design transition to two tunnels showing obliquely small net distance, that is, two tunnels, the minimum distance between the two tunnels is controlled at 3 ~ 5m Until the transition to the "Lu" glyph, the upper and lower small net spacing form, that is, two tunnels are arranged, the vertical closures between the upper and lower tunnels are controlled at 2 to 3m; C, then they will be small b...

Abstract

The invention aims to provide a mining method tunnel excavation method for transition from a separation type to a lamination type. A horizontal relation separation type mining method tunnel is transited into a horizontal small-clear-distance tunnel through a plane linear design, the horizontal small-clear-distance tunnel is transited into a vertical small-clear-distance tunnel through a plane linear design and a longitudinal plane linear design, the vertical small-clear-distance tunnel is transited to a vertical overall laminated tunnel through a plug wall, the structural height of the overall laminated tunnel is compressed through the longitudinal plane linear design, and finally the width of the tunnel structure is reduced. Through the conversion, construction of mining method tunnel engineering with wide construction environment conditions transited to narrow and limited construction environment conditions can be met.

Description

Technical field [0001] The present invention relates to a mine tunnel engineering for construction environmental conditions by a separating transition to a laminate mine method, which is suitable for construction environmental conditions from a mine law tunnel engineering from a wide range of transition to narrow restented conditions. Background technique [0002] In the construction of the mine method, under the circumference of the surrounding environment, the form of a tunnel in the form of a horizontal separation can be employed; the form of a vertical integral laminate can be employed under the condition of the surrounding environmental stenosis. However, when the surrounding environmental conditions are transitioned from a beyond to stenosis, there is a transition and conversion of the above two tunnels, and there is no clear technical solution in China. Inventive content [0003] It is an object of the present invention to propose a method of excavation of the separated t...
