Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] A method and a filling process for superelevation under-mining filling and roofing of an upward approach, including the following steps:

[0021] 1. Preparation

[0022] (1) A detachable composite panel wall 5 is installed at the outer mouth of the goaf. The detachable composite panel wall 5 uses geotextiles for water filtration, and a second panel wall 8 is installed on the outside of the detachable composite panel wall 5 and is covered with geotextiles. For secondary water filtration, the distance between the detachable composite board wall 5 and the second board wall 8 is 5m-10m. Such as figure 1 shown.

[0023] (2), install the water discharge tee 6 on the cross brace of the second board wall at the junction of the filling main road 7 and the second board wall 8; figure 2 As shown, the water discharge tee 6 includes a main pipe ...

Abstract

The invention discloses a filling roof connecting method used for upward drift ultrahigh undersampling. An upward horizontal layered drift filling mining method includes the following steps that firstly, a stope is arranged; secondly, filling pipes, gas return pipes and a marking pipe are erected, and a detachable combined board wall is sealed; thirdly, a quick switch blade type self-locking filling and water draining tee joint is installed for conducting filling operation; and fourthly, dewatering is conducted, the gas return pipes are bent, and forcible roof connection is conducted. By the adoption of the method, the problem about roof connection of ultrahigh undersampling filling drift is completely solved; through reasonable erection of the filling pipes, the gas return pipes and the marking pipe, selection of a proper filling material and preparation of the filling material of the method, filling slurry is good in water permeability, relatively low in natural settlement shrinkage rate and relatively good in fluidity and has good application prospects and high social value.

Description

technical field [0001] The invention relates to a filling and roofing process of an upward horizontal layered approach filling mining method with uneven roofs, belonging to the technical field of underground mining. Background technique [0002] With the development of mining technology, shallow resources are gradually exhausted, and mining is transferred to deep mining, and the proportion of filling mining is increasing day by day. The filling method can not only minimize the loss and dilution of ore, reduce the mine ground pressure, and ensure the safety of mine production, but also timely dispose of production waste rock and tailings, effectively reducing the impact on the ecology and protecting the surface from damage. However, the filling mining method has the problems of high labor intensity and low filling and roof connection rate, especially the development of underground joints, broken rocks, and the limited technical level of some workers, which have caused serious...
