Please submit, as an exhibit of your bond release, a map that superimposes surface cracks <br />and other subsidence features, H-seam workings, F-seam workings, significant and <br />recognizable surface features (roads, railroads, etc.), and structural contours of the F- <br />seam (in the areas of F-Seam workings) for the W%2 Sec 31 T6N R91 W and an equivalent <br />area (1/2 Section is size) contiguous to the west (R92W). Please keep the scale of the <br />drawing larger than 1 inch equals 250 feet. Please color code the above features. <br />Please provide the initiation and drawdown elevations of the xxx pump and the yyy <br />pump, and the divide elevation for hydraulic communication between the F and <br />underlying E seam workings. <br />The purposes of these requests are to illustrate the spacial relationships of the subsidence <br />features to H-Seam and F-Seam workings, and to determine if areas of F-Seam workings <br />located near or under subsidence features are (or were) subject to alternate flooding and <br />dewatering from pumping activity.
