Mining device of steeply inclined thin ore deposit and deep hole rock drilling stage chamber method using same

Abstract

The invention discloses a mining device of a steeply inclined thin ore deposit and a deep hole rock drilling stage chamber method using the mining device. The mining device comprises a rock drilling and pedestrian courtyard, a ladder, ladder compartment safety platforms, guide rails and a liftable rock drilling platform, the rock drilling and pedestrian courtyard is arranged in studs on two sides of an ore block corresponding to the inclination of an ore body; the bottom of the ore body is provided with an undercut roadway parallel to the trend of the ore body, the undercut roadway communicates with the rock drilling and pedestrian courtyard, a footwall of the ore body is provided with a stage transportation roadway corresponding to the trend of the ore body, the stage transportation roadway and the undercut roadway are communicated through an ore removal access, and the ladder is fixedly connected in the rock drilling and pedestrian courtyard and close to one side of footwall surrounding rock. The ladder compartment safety platforms are distributed on the outer side of the ladder at intervals corresponding to the inclination of the ladder, the guide rails are fixed to the sides, away from the ladder, of the ladder compartment safety platforms, the liftable rock drilling platform is slidably connected to the guide rails, horizontal deep holes are formed in the direction parallel to the ore body, one end of each horizontal deep hole communicates with the rock drilling and pedestrian courtyard, and the horizontal deep holes are filled with explosives.

Description

technical field [0001] The invention relates to the technical field of underground mining of metal ore deposits, in particular to a mining device for steeply inclined thin ore deposits and a deep-hole rock drilling stage mine method using the same. Background technique [0002] Steeply inclined thin ore bodies with a dip angle of 65°-80° and a thickness of 1-4m occupy a considerable proportion of precious metal and non-ferrous metal ore deposits in my country. For such deposits, the method of wall cutting or shallow hole retention is often used for mining . The main problems of these mining methods are: personnel work in a large empty area, there is a risk of surrounding rock collapse in the empty area, the safety is poor, the mining process is complicated, it is not easy to manage, the labor intensity of the operators is high, and it is difficult to realize safe and efficient mechanized mining , The ore is stored for a long time, which is not conducive to rapid recovery of ...
