specific Embodiment approach

[0044] After the filling of the first section 101 is completed, personnel enter the rock drilling tunnel B21 of the second section 102, and make a layer of cemented surface 10 with a thickness of 0.5 m on the filling body 11; , to carry out the mining operation; the mining method of the second section 102 and the third section 103 is the same as that of the first section 101; B15 goes to the subsection connecting cross alley A5, and the subsection connecting cross alley B14 is transported to the slip mine A4 and the mine slip shaft B18 for ore discharge. All the ore is finally discharged through the stage transport road 1; the filling material is discharged from the filling ventilation shaft 7 in the vein. , mined and filled from bottom to top by subsection. The specific implementation is as follows:

Embodiment

[0045] Example: the ore body 9 is vertically divided into several stages of ore blocks along the direction of figure 1 The first section 101, the second section 102 and the third section 103 are shown in three sections, and the top column 8 is reserved at the top of the third section 103, and the thickness of the top column 8 is 2.5m; Figure 2-4 As shown, in the middle position of the stage ore block on the side of the lower wall and parallel to the ore body 9, an in-vein filling ventilation shaft 7 is opened. The cross-section of the in-vein filling ventilation shaft 7 is a rectangle of 1.5m×2m. From left to right 2 / 3 of the end, excavate a stage transport roadway 1 parallel to the stage ore blocks; from the middle position of the stage transport roadway 1 corresponding to the stage ore blocks direction to the direction away from the stage ore blocks, excavate a horizontally arranged concentrated mine Level road 17,; from the stage transport road 1 to the position 4.5m away ...

Abstract

The invention discloses a trackless mining method for a gently inclined vein by adopting a rockhole ore removal system as a ramp. The trackless mining method comprises the following steps: ore body dividing, ventilation shaft arranging, ore removing and laneway excavating, laneway constructing, primary ore removing, primary stoping and filling, secondary ore removing, secondary stoping and filling, tertiary ore removing and tertiary stoping and filling. The trackless mining method can mine gently inclined medium stable veins well, and can effectively solve the problems, in a traditional mining method, that the prepared ore reserve is large, the construction period is long, the consumption of manpower and material resources is high, and the cost is high. The trackless mining method has the advantages of small prepared ore reserve, high mechanization degree, high safety, small resource loss and waste, high working efficiency and the like.

Description

technical field [0001] The invention relates to a trackless upward layered filling mining method, in particular to a trackless mining method for gently inclined ore veins using an out-of-vein ore-out system as a ramp. Background technique [0002] Gently inclined ore veins are one of the main forms of occurrence of non-ferrous metal ore veins in my country, especially in gold, silver, molybdenum, tin, tungsten, antimony and other deposits. This kind of gently inclined ore vein has problems such as difficulty in controlling the boundary of the ore body, high loss rate and dilution rate, and difficulty in handling the ore after blasting. However, these two mining methods are difficult to adapt to the complex and changeable mining technical conditions of lode deposits, and are prone to problems such as difficulty in controlling the boundary of the ore body, high ore loss rate and high dilution rate. There is also a mining method called upward layered filling mining method. Thi...
