摘要： A method for mining high grade ore from an ore body uses a near horizontal hole. The horizontal hole is bored into the ore body through as many of the high grade portions as possible. A jet mining tool is inserted into the hole to the high grade portion farthest from the tool insertion location and that portion of the high grade ore is removed. The tool is then pulled out of the hole until the jets are in a high grade portion which is adjacent the high grade portion previously mined and this portion is then jet mined. The process is repeated until all of the high grade portions of the ore body have been mined. The mined material is removed through the horizontally bored hole.
