Dept. of Natural Resources <br />November 4, 1981 <br />Mr. Robert Liddle <br />Mined Land Reclamation <br />Department of Natural Resources <br />1313 Sherman Street, Room 423 <br />Denver Co. 80203-2273 <br />Re: Mine No.3 conveyor splash pan installation <br />North Thompaon Creek Mines, File No.C-025-81 <br />Dear Bob: <br />Following the i~tallation of approximately 100 feet of the <br />splash pan system in accordance with the approved plan, we <br />came to the realization that this design created a considerable <br />hazard due to the fact that the bottom edge of the pan extended <br />out over the road at approximately the windshield level of <br />large vehicles such as dump trucks,-etc. We therefore wish to <br />modify the design of our splash pan system. Our proposed <br />modification will enable us to contain and control all coal <br />fines which might fall from the conveyor belt while eliminating <br />the above described hazard. <br />The proposed design consists of a 48 inch wide, 11 gauge, <br />steel plate welded to the conveyor support frame wotk below <br />the conveyor belt. 4 inch high side plates of the same material <br />will be welded along the length of this bottom plate. The <br />pans will be overlapped in a manner to form a continuous <br />trough below all portions of the conveyor belt which over- <br />hang the streambank. <br />The pans will be washed periodically with water which, upon <br />reaching the lower end of each trough segment, will fall onto <br />the sloped road surface and flow into drainage ditch D-2 <br />which parallels the road. This water will further be~prevented <br />from flowing over the steambank by an earthen berm which <br />presently is installed along the top edge of the streambank <br />from the mine No.3 area down to the general vicinity of the <br />electrical substation. <br />Our proposed design will also allow us to keep the temporary <br />(brattice cloth) splash pans in place until the permanent <br />installation is completed. <br />I have attached a drawing of our proposed modification fol' <br />
