The height of the stage bracket filling method is generally 25 to 30 m. When the thickness of the steeply inclined ore body is less than 10 m, if the ore and surrounding rock are slightly stable, the section height of 50 to 60 m may be taken.
Most of the mining work of the box bracket filling method is arranged in the mine body, and the sampling ratio of 1000 tons is 30-40m. The stage transportation lanes are excavated in the surrounding rock of the ore body. When the ore body is very thick, it is generally necessary to dig a tunnel in the center of the ore body, and tunnel the tunnel to the width of the vertical strip or the width of the mine, and thereby dig up the filling patio. The patio size is generally 1.5 x 2.1 m, divided into three compartments. The patio is generally arranged near one of the upper and lower plates, and the vertical dividing scheme is to arrange a two-grid patio in the center of the ore body. With the upward recovery, the side frame is used to set up the mine and the sidewalk.Our Replacement Parts for Cornheaders">Replacement Parts For Cornheaders is good in quality and competitive in price.
