Title: Method for mining inclined ore bodies
Inventor: FATKULIN A A
IPC: E21C41/22
Filed: 1996-12-03
Granted: 1998-07-27
Abstract: FIELD: mining industry. SUBSTANCE: this can be used for mining inclined ore bodies primarily of medium thickness with disseminated ores when mining contours are determined according to test data, and rock matter remaining beyond mining contour is metal-bearing. According to method, mining section is divided into chambers which are oriented in dipping. Undercutting space is arranged in lower part of chamber with creation of ore receiving drifts below undercutting space in underlying rock matter. Bore-holes are drilled from inclined drilling raise driven along contact with lying wall. Ore is broken layer-by-layer with delivering it by blasting method to ore-receiving drifts. Breaking of ore layers is carried out with cutting rock matter of roof in amounts sufficient for making aforesaid roof with profile which corresponds to flying trajectory of high-thrown pieces of ore cut loose from final layer of chamber. This meets requirements of moving ore pieces through space of earlier broken layers when extracting thickness of ore body in section of flying is less than flying height. At breaking of ore layers which are distant from ore receiving drifts, plane of entire work face is oriented as inclined at acute angle with respect to lying wall towards rock mass. Application of aforesaid method allows for increasing range of throwing ore in stoping space. EFFECT: higher efficiency. 3 dwg
