[0009] Finally, certain mining areas may be bounded by boundaries such that only one side of the mining area is controlled through lease or ownership, while the other side of the mining area is not
This places a huge burden on miners who wish to exploit deposits under their own control

Embodiment Construction

[0045] The present invention provides an economical and convenient mining system suitable for quick and efficient removal of ore deposits from deposits with a minimum of downtime. The ore deposit mining device and method combine open-pit strip mining with underground longwall or shortwall mining techniques. More specifically refer to Figure 5 The mining system of the present invention utilizes open pit strip mining to create stable sides 502 and stepped areas 503 around the deposit 501 to allow the mining system to be inserted underground. However, open-pit strip mining is implemented in stages: starting with zone A between lines a and aN, followed by zone B advancing to lines b and bN, followed by subsequent open-pit steep-slope strips, each strip increasing by approximately 200 feet to 500 feet to the end of deposit 501. Typically, the width of the stepped area 503 is between 80 and 100 feet.

[0046] Also refer to Figure 5a , the mining system begins constructing an i...

Abstract

A method for extracting mineral deposits in a mineral reserve (1501), a portion being accessible from a sloping surface and the remaining portion being inaccessible, is disclosed. The sloping surface is mined to create a bench (1515) and highwall for providing access to the mineral reserve around the accessible portion. A surface is formed in the highwall to create an insertion highwall (1520) between an endwall extending from the insertion highwall and the inaccessible portion (PB) of the mineral reserve. A starter entry (1580) is created for cutting into the mineral reserve across the entire length of the insertion highwall from the endwall to the inaccessible portion of the mineral reserve (1501). Roof supports are advanced into the starter entry with spoil added to form a starter passage from the endwall to the inaccessible portion of the mineral reserve. Shortwall or longwall mining techniques are then used to mine the mineral reserve along the starter passage.

Description

technical field [0001] The present invention relates generally to a mining system for mining a mineral deposit, more particularly, but not limited to, a mining system combining open pit strip mining and an underground shortwall or longwall mining system. Background technique [0002] Traditional surface mining systems have devastating environmental consequences. In hilly or mountainous areas, open pit strip mining is accomplished by removing timber and clearing the area to be mined, and cutting a strip to form substantially horizontal terraces and vertical sides, exposing the layer of deposit to be removed. Another technique involves removing just the entire top of a mountain to extract minerals deposited below. [0003] Underground mining systems are less environmentally damaging, but are more costly, less efficient and have lower productivity. When an underground mining system is used to extract ore deposits or coal beds from a deposit or coal mine 10, the mine 10 is div...
