Description
Technical Field
the invention relates to a mining technology, in particular to a method for qualitatively determining a local area of mineral resources.
Background
In the evaluation of regional and regional mineral resources, the geological data used belong to continuous quantitative geological variables. Many geological phenomena, however, do not have a strict range of quantitative variation, nor do they have an adequate quantitative method, which represents only a qualitative concept of a geological phenomenon. The geological phenomena are closely related to the action of mineralizing geology, and play an important role in establishing a quantitative model of the relation between the mineral resource quantity and the geological conditions.
The invention is used for providing a qualitative method for the local area of mineral resources, so as to provide a convenient plan for mining mineral from the local area of qualitative ore.

A mineral resource local area qualitative method comprises the steps of designing and drilling, erecting a workbench, blasting an area and finally performing qualitative process, and comprises the following steps:
1) designing a drill hole: utilizing early exploration to draw a basic mineral resource exploitation plan map for an area, drilling holes at qualitative points to drill two determined main cracks on a surface rock layer, and determining a wiring map for deep hole filling blasting in the mineral resource exploitation plan map;
2) Erecting a workbench: establishing a workbench by utilizing the drawn mineral resource exploitation planning map, wherein the workbench is positioned below an angular bisector between the two determined main crack systems, and the edge of the workbench is set to have an angle of 90 degrees with the impact positioning;
3) Area blasting: firstly drilling additional compensation holes without explosive at a distance of 4 to 6 diameters from the hole of the hole to be blasted, as a result of which a cutting compensation chamber is formed; then, continuously performing delayed blasting on the drilled formed compensation cavity; thereafter, the residual mass of pit ore accumulation is ejected by short delays between mining deep hole ore groups; thus, a partial section of the lump qualitative ore is formed which is not explosively distributed on the working table, the crushing height of the crushed rock is equivalent to the height of the working table, and the ore of which the mining runs after the second diverting mining is obtained;
4) And (3) final characterization: the ore obtained in the blasting process is discharged to the free surface above the blasting area, so that the blasted deep hole is tested by a geophysical method, the natural block structure of the rock mass is explored, and the map qualitative ore of the rock mass is drawn.
Compared with the prior art, the invention has the beneficial effects that: the method can rapidly determine the position of the resources in the mineral area and draw the map-determined ores of the rock mass, thereby providing great convenience for mining production in the mineral area.
