摘要： Deposits, such as coal, tar sand, heavy crude oil and/or minerals are excavated from an underground formation layer (4) by:—inserting a chain cutter string (11) into a 1st section (8, 9) and a control cable (12) into a 2nd section (10) of a T-, V-, U-, or L-shaped channel assembly (8, 9, 10) traversing the layer (4);—connecting the control cable (12) to the chain cutter string (11) at a branchpoint (13) of said 1st & 2nd sections (8, 9 & 10); and—pulling the chain cutter string (11) in a continuous or oscillating manner through the first section (8,9) while continuously pulling the control cable (12), such that the chain cutter string (11) carves deposits from the layer (4) and the control cable (12) optimizes the performance and reduces the risk of breakage of the chain cutter string (11).

摘要： A rotating and indexing mechanism (10) having two spaced apart, rows of toothed profiles (48, 52) which form camming surfaces for two spaced apart rows (62, 64) of cam followers (32). The toothed profiles (48, 54) and cam followers (32) are such that when there is relative movement between the toothed profiles (48, 54) and the rows (62, 64) of cam followers (32) in one direction, the camming action of the cam followers and toothed profiles pause incremental rotation of a shaft (16). A groove (66) is also provided for locking the two profiles and cam followers together when the desired incremental (index) position is reached.Two embodiments are shown, one where the toothed profiles are moved axially to give rotation to the cam followers and shaft, and the other where the cam followers move axially to give rotation to the toothed profiles and the shaft.
