Partition combined cut-and-filling stoping method

Abstract

The invention discloses a partition combined cut-and-filling stoping method, which includes the following steps: step 1, arranging a stope: dividing the stope into a front left stope and a rear rightstope along the trend of the ore body, and dividing the stope into three sections in the vertical height direction and dividing each section into three layers: step 2, constructing a transverse drifting prospecting lane to a bottom column to the vertical ore body, performing construction to a measurement inclined shaft from the stope boundary to the position above the bottom column, constructing undercutting level along the ore body trend at the position above the bottom column and near the measurement inclined shaft, then constructing a filling return air shaft inside the stope near to the lower section, and communicating the two sections at the upper part; step 3, constructing a lode outer slipping shaft and a pedestrian drainage well from the transverse drifting prospecting lane, takingthe undercutting level as a free face, then respectively performing primary lamination and secondary lamination stoping inside the two subsection stope layers, then performing stoping layer by layer;erecting the pedestrian drainage well, laying an artificial false bottom and filling an undercutting layer after the stoping is finished. The method has the advantages that the structure is simple, the construction is reasonable, the stoping efficiency is high, and the two adjacent stopes can be combined for combined stoping.

Description

technical field [0001] The invention relates to the technical field of underground mine mining engineering, and in particular relates to a filling mining method, which is particularly suitable for the safe and efficient recovery of the subregional combined filling mining method of ore with average ore value and thin to medium-thick inclined ore bodies. Background technique [0002] With the tightening of national safety and environmental protection policies, more and more mines use the filling and filling mining method in underground mining. In the mining of average ore value, thin to medium-thick inclined ore bodies, the layered filling method is the most commonly used method. This method needs to reserve a bottom column, and each stope must set up a mining and cutting project, including out-of-vein Compared with other mining methods such as approach method, staged deep hole and subsequent filling method, for projects such as pedestrian water filter wells, filling ventilati...
