And reach the effect of spalling rock mass.
The method research and development of the exploitation stone ore of the present invention need to be familiar with the spalling mechanism that pillar hydraulic pressure in hole splits stone implement, Yi Jiyu
Other hydraulic pressure split the contrast of stone implement;It is familiar with rock mechanics and rock engineering (explosion, well lane engineering);It is familiar with specific engineering to appoint
Business, such as the defects of the geology of stone digging and geomorphologic characteristics, the exploitation requirement of stone material, existing production technique etc..Therefore this hair
The method of bright exploitation stone ore is to be developed in inventor after largely testing and overcoming larger technical difficulty.
For example, inventor is established using the basic hole of varying number by the use of FEM-software ANSYS is used as the spalling scope of freedom
Computation model, pillar hydraulic swelling technology force analysis in hole when Research foundation hole number is different, i.e., basic hole number difference
When finite element model solve result of calculation stress analysis.
By the first principal stress cloud atlas in the basic hole to varying number, equivalent stress nephanalysis, varying number is obtained
The first principal stress in basic hole, the maximum of equivalent stress and its there is position, thus:1st, basic hole number and spalling are found
The relation of effect;2nd, when first principal stress is more than the saturated uniaxial compressive strength value of rock, pillar hydraulic pressure splits stone implement in hole
Under the action of, rock can be by drawing crack easily;3rd, the relation of equivalent stress maximum and basic hole number is found;4th, due to etc.
Efficacy is much larger than the single shaft saturation tensile strength values (generally 7.0~25.0MPa) of rock, therefore pillar hydraulic pressure is split in hole
Under the action of stone implement, rock can be easily broken.
By the use of FEM-software ANSYS establish using variety classes rock, varying number basic hole (emptying aperture) as swollen
The computation model on the scope of freedom is split, obtains cloud atlas, the equivalent stress cloud atlas in the asynchronous first principal stress direction of Rock Species.Utilize
FEM-software ANSYS establishes the static spalling model of operation hole and basic hole (emptying aperture), passes through first principal stress field, the 3rd master
Stress field, displacement vector and cloud atlas, spalling mechanism of the analysis operation hole to basic hole (emptying aperture).Utilize FEM-software ANSYS
Establishing has the spalling model on second scope of freedom, and physical model is calculated, and show that rock material produces under function load action
Raw fractue spacing, realizes the process that pillar hydraulic pressure in hole splits rock crusher drawing crack during stone implement static state spalling of simulating, it was demonstrated that
Pillar hydraulic pressure splits validity in stone implement exploitation stone material etc. in hole.
As shown in figure 3, Fig. 3 is the flow diagram one of the method for the exploitation stone material of an embodiment of the present invention.With reference to figure
3, the method for exploitation stone material of the invention mainly includes the following steps that:
Step S10, pillar hydraulic pressure in hole is provided split stone implement, pillar hydraulic pressure, which splits stone implement and includes first group of expansion, in the hole fills
Put;
Step S20, the first hole group is formed on first scope of freedom of matrix to be exploited, the first hole group includes and first group
Several matched the first operation holes of expansion gear;
Step S30, several first foundation holes, and the first operation hole are formed on first scope of freedom of matrix to be exploited
It is arranged to enclose the setting shape for being set as allowing stone material to peel off from matrix with first foundation hole;
Step S40, first foundation hole is kept to be inserted into corresponding first operation hole for dummy status and by first group of expansion gear
In, and pillar hydraulic pressure is split stone implement action, so that spalling goes out to set the first to be removed of shape on matrix to be exploited
Stone material.
It should be noted that rock system hard brittle material has the evident characteristic that tensile strength is much smaller than compression strength.Mirror
In this, in the inventive solutions, the rock spalling technology of stone implement is split by using pillar hydraulic pressure in hole to complete stone material
Mining operations, it is clear that split that the expansion gear of stone implement overcomes during completing to exploit stone material is the tensile strength of rock,
