Definitions
- the invention relates to the technical field of coal mining, in particular to a method for controlling the surface subsidence of a goaf in a mine with a "three down" coal mining and a relatively stable coal seam roof.
- the domestic and international aspects mainly start from the aspects of subsidence mining and roof movement control of goaf overburden:
- the mining technology mainly includes strip mining and room-column mining.
- Strip mining is to divide the mined coal seam into more regular strips, and then take a strip to reduce surface subsidence.
- This technology is widely used in China. Its biggest advantage is that it can follow the existing coal mining process, with less cost increase and easy production management. At the same time, it has a significant effect on reducing surface settlement. Its shortcoming is mainly due to low production rate (generally From 30% to 50%), the resource loss is serious.
- Room-column mining is a relatively mature coal mining technology used in the United States, Australia, South Africa, etc. It is not only a conventional coal mining method, but also a mining method for surface subsidence control. This method has application in some mining areas in China, and its economic benefits.
- the disadvantages are low resource recovery rate and poor ventilation conditions, which are only applicable to coal seams with relatively simple geological conditions;
- the roof overburden movement control technology in the goaf mainly includes all filling techniques, partial filling techniques, separation grouting technology, and filling and grouting technology in the caving area. All filling techniques use filling materials to fill the goaf to form a filling body, thereby preventing the roof from falling and restricting the movement of the roof. This method can effectively reduce the surface subsidence and increase the coal recovery rate, but because of its high cost. Very limited. Partial filling technology is to fill the local or separated zone and the falling zone of the goaf, and control the mining subsidence by supporting the overlying strata with the key layer structure of the overburden, the filling body and some coal pillars.
- the separation grouting technology starts from the internal movement law of the rock stratum, determines the position of the overburden strata after the mining, and fills the medium with the fly ash and other medium from the surface drilling to the separation layer, so as to achieve the purpose of controlling the surface subsidence.
- Grouting and parallel mining work in parallel do not interfere with each other, but the application of the separation position and the amount of separation is difficult to accurately determine and is limited in application.
- the grouting filling technology in the caving area is to fill and reinforce the rock in the goaf before it is compacted, so as to support the overburden and slow down the surface subsidence. The technology is still in the research stage and has not been widely used. .
- the research on coal mine filling technology should make full use of the movement law and control characteristics of coal-bearing layered rock layers.
- the relevant research proves that the key layer of overburden plays a role in controlling the surface movement process.
- the breaking of the main key layer will lead to the rapid subsidence of the surface and the obvious increase of the subsidence.
- the surface subsidence speed will be periodically broken with the main key layer. Jumping changes.
- controlling the main key layer can effectively control surface subsidence.
- the object of the present invention is to overcome the deficiencies in the prior art and to provide a method for controlling surface subsidence by using a partial filling of a goaf in a simple method, convenient operation, and low cost.
- the method for partially filling and controlling surface subsidence of the goaf of the present invention comprises the following steps: a. arranging a concrete conveying pipe in a working surface transportation roadway, and installing a concrete conveying pump on the downhole working surface equipment train at work a filling pipe connected to the concrete conveying pipe is suspended on the tail beam of the surface hydraulic support, and a plurality of filling regions are arranged at intervals between the hydraulic supports at the lower end of the working surface, and a discharging port is arranged at a filling pipe position corresponding to each filling region;
- the metal mesh is suspended from the top plate behind the hydraulic support on the working face, and a filling bag is arranged in the metal mesh;
- step ⁇ d to complete a filling cycle. Forming a row of filling bodies in the goaf parallel to the working face;
- the invention adopts a partial filling mining method on the basis of strip filling, which can reduce the filling amount and filling amount of the filling material and reduce the filling cost.
- the top plate of the goaf is evenly supported, which is beneficial to the stability of the roof and the key layer.
- the filling of rectangular areas in the goaf evenly reduces the filling amount, reduces the filling cost, improves the recovery rate, and improves the stability of the key layer of the overlying strata, so that the surface subsidence can be effectively controlled.
- the method is simple and low in cost.
- the concrete conveying pipe 3 is arranged in the working face transportation lane 2, and the concrete conveying pump is installed on the downhole working surface equipment train 9, and the filling pipe connected with the concrete conveying pipe 3 is suspended on the working face hydraulic support tail beam. 4, a plurality of filling areas are arranged between the lower end hydraulic supports on the working surface, and a discharging port 5 is arranged at the filling pipe 4 corresponding to each filling area;
- the metal mesh is suspended at the top of the working face behind the hydraulic support, and a filling bag is placed in the metal mesh.
- the length of the metal mesh on the side perpendicular to the direction of advancement of the working surface is 4 to 5 m, and the width on both sides parallel to the advancing direction is 0.6 to 0.8 m;
- step ⁇ d to complete a filling cycle.
- a row of filling bodies 10 is formed in the goaf parallel to the working surface, the filling cycle step is 1.2 ⁇ 1.6 m, which can be adjusted according to the actual situation on the site, and finally a filling body 10 with a certain strength is formed;
- the propulsion length is 2.4 ⁇ 4 m, which can be adjusted according to the actual situation.
- steps d and e to continue the filling operation of the next cycle, and repeat until the entire gob area is completed.
- the filling operation causes the goaf to form a plurality of rows of filling bodies 10.
