Mining and filling combined hydraulic support system

Abstract

The invention discloses a mining and filling combined hydraulic support system comprising filling auxiliary devices and filling auxiliary supports. The filling auxiliary supports are located in front of the filling auxiliary devices, connected with the filling auxiliary devices and used for pulling the filling auxiliary devices. Each filling auxiliary device comprises filling auxiliary units. Each filling auxiliary unit comprises a top beam, a base, a guide column and two hydraulic vertical columns, wherein the guide column and the hydraulic vertical columns are connected between the top beam and the base, and the guide column is located between the two hydraulic vertical columns; filling pipe seats are arranged at the front ends of the bases; and hanging pieces used for hanging filling moulds are arranged on the sides of the top beams. Mined areas do not need to be overall filled, room-column type filling is adopted, the moulds are filled with mixtures capable of being rapidly solidified, mining and filling can be conducted simultaneously, the filling time can be shortened, the filling cost can be reduced, and the filling efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of coal mining equipment, and in particular relates to a mining-charging combined hydraulic support system. Background technique [0002] After decades of mining of coal resources in China, the coal seams with good conditions and easy mining are almost exhausted. [0003] In order to improve the service life of major coal mines and make full use of underground coal resources, the reform of fully mechanized mining and filling in coal mines in my country has developed rapidly, and the development of fully mechanized mining and filling technology in coal mines has reached an unprecedented level. It is an important link that plays a key and pivotal role in coal production and safety assurance. However, the traditional filling process is realized by filling the entire mining area, resulting in a waste of time, financial resources, and material resources. Obviously, the conventional filling mining process cannot m...

Problems solved by technology

However, the traditional filling process is realized by filling the entire mining area, resulting in a waste of time, financial resources, and material resources. It is obvious that the conventional filling mining process cannot meet the development of future filling mining. Therefore, a solution to the above problems A new filling process came into being. It is not necessary to fill all the mined areas. The room-pillar filling is used to fill the mold with a mixture that can solidify quickly, which can shorten the filling time and improve the mining efficiency.
