The Forecast Of Mineral Resources Based On Data Mining Technology

With the changes in coal prices, some mines abroad implemented underground toopen pit mining.However, the original underground mines left a large number of differentand complex gobs plaguing many mines.It is an important issue about how to delineate theimpact area and the depth of mined-out area.This paper aiming goaf`s scope、depth used Ordos City Ulan Coal Corporation TelBrad mine for the study and transient electromagnetic method detection technology, byapplying different weights assigned mine rock on the range of clear mined areas with largemining trucks machinery and equipment to indenty the study erea withstand weight of therock forming limit. Research had these areas:(1) Through the mine site survey determined the scope of the experimental area andused GPS-RTK lofting inflection coordinates.(2) ATEM-10KW transient electromagnetic transmitter and ATEM-IV transientelectromagnetic receiver were used in the experimental area and used overlapping loopmethod for goaf detection work.(3) Respectively using Grapher4.0, ATEM-2pro, Voxler3and Surfer8in view of thedetection results were analyzed, and concluded that apparent resistivity contour map andthe underground mined-out area3d sketch map.(4) In view of the3d sketch map, usd FLAC-3D to establish model of the mined-outarea, selected six geotechnical medium seriously damage stress environment andunderground complex surface weak position, applying for the weight of different tonnageof mine driving load, ultimate bearing is calculated for each position, finally it is concludedthat the surface the weakest position to withstand the weight of the largest miningmachinery and equipment of248t.Using the transient electromagnetic method, this paper selected the spatial location,shape, thickness has clear mined-out area, applying different weights assigned strata on themining truck and other large-scale mining machinery and equipment, and analyzed itsultimate bearing capacity what has has important realistic and long-term significance for Tel Brad mine even other similar geological conditions mined-out area of the mine safetyproblems.
