28. Types of plans and sections:

  1. The owner, agent, mining engineer or manager of every mine shall keep the following plans and sections-
    1. a surface plan showing every surface feature within the mining lease boundaries, such as building, telephone, telegraph or power transmission line, watermain, tramline, railway, road, river, water-course, reservoir, tank, bore-hole, shaft and incline opening , opencast working, dumps and dumping ground, the waste land, forest, sanctuaries, agricultural land and grazing land and subsidence on the surface.
    2. a surface geological plan of the area of leasehold, on a scale specified or approved by Controller General by a general or special order in writing showing-
      1. all the lithological units exposed in the area, in the pits, trenches and in any other openings made for prospecting and mining operations showing contact between lithological units;
      2. structural details like strike, dip, fold, fault, plunge of ore body;
      3. location of prospecting pits, trenches, boreholes and any other openings made for prospecting and/or mining operations;
      4. existing mine workings, dumps.
    3. a transverse section or sections of the workings through the shaft or shafts and main adits indicating clearly the strike and dip of the vein, lode, reef, or mineral bed or deposit at different points, and such sections of the strata sunk or driven through in the mine or proved by boring, as may be available;
    4. a longitudinal mine section or sections showing a vertical projection of the mine workings including outlines of all stoped out areas, where a reef, vein, lode or mineral bed/deposit or part thereof has dip exceeding thirty degrees from the horizontal plane:

      Provided that, with the permission in writing of the Controller General or the Chief Controller of Mines, as the case may be, and subject to such conditions as he may specify therein, such sections may be prepared in relation to any other suitable plane.
    5. an underground plan showing-
      1. the position of the workings of the mine below ground;
      2. every borehole and shaft (with depth), drive, cross-cut, winze, raise, excavation(stoped ground) and every tunnel and air passage connected therewith;
      3. every pillar or block of mineral left for the support of any structure on the surface; and underground magazines, if any;
      4. the general strike of the veins, lodes, reefs and mineral beds or deposits;
      5. the position of every dyke, fault and other geological disturbance with the amount and direction of throw.
  2. Whenever the underground plan referred to in clause(e) of sub-rule(1) is brought up-to-date, the then position of the workings shall be shown by a dotted line drawn through the ends of the workings, and such dotted line shall be marked with the date of the last survey:

    Provided that that Controller General or the Chief Controller of Mines, as the case may be, may, by an order in writing and subject to such conditions as he may specify therein approve any other method of showing the up-to-date position of the workings of the mine.
  3. Where different reefs, lodes, veins or mineral beds or deposits overlie or run parallel to one another, the workings of each reef, lode, vein or mineral bed or deposit shall be shown on separate plan and/or longitudinal section or sections; however if two reefs, lodes, veins, or mineral beds or deposits are so situated in relation to each other that the parting between workings made therein is less than ten metres at any place, such workings shall also be shown on a combined plan and/or longitudinal section, as the case may be, in different colours.
  4. The plans kept under clauses(a) and (e) of sub-rule (1) shall also show the settled boundary of the mining lease, or where the boundary is in dispute, the boundaries claimed by the owner of the mine and by the owners of the mines adjacent to the disputed boundary:

    Provided that where it is not possible to show the complete boundary of leasehold on the same plan an additional key plan on any other suitable scale showing such boundaries and the outline of the workings shall also be maintained.
  5. The owner, agent, mining engineer or manager of every mine shall keep the following:
    1. A key plan on a scale of 1:63,000 or 1:50,000 incorporating the following:
      1. an administrative surface map showing the boundary of the mining lease, and the adjoining area lying preferably within five kilometres thereof;
      2. Contours at not more than twenty metres intervals;
      3. Natural drainage system such as rivers, streams, nalahs, water reservoirs, ponds, lakes, irrigation dams and canals;
      4. Roadways and railways;
      5. Places of historical and archaeological importance, monuments, places of worship, pilgrimage and of tourist interest;

    2. An environment plan of the area of mining lease inclusive of the adjoining area within five hundred metres of the boundary of a lease area on 1 : 5000 scale incorporating the following:
      1. An administrative surface map showing the boundary of the mining lease;
      2. Contour lines at five metres intervals;
      3. All features indicated in sub-clauses (iii) to (ix)of clause (a) above;
      4. Area occupied by mine workings, area deforested, area covered by dump with the height of the dump, processing plant, surface building, workshop, mining township;
      5. Area reclaimed and area afforested, location of protective barriers, check dams erected to contain solid and liquid effluents generated by prospecting, mining, beneficiation or metallurgical operations carried out in the mine;
      6. All pumping stations and the courses of discharge of mine water.

      Provided that the particulars with regard to items (ii), (iv) and (v) shall be applicable only upto sixty metres beyond the boundary of lease area.
  6.  
    1. The Controller General may, by an order in writing, require such additional details to be shown on the plans and sections required to be kept under these rules or the preparation and maintenance of such plans and sections showing such details and on such scale and within such time as he may specify in the order.
