(1) Every coal lease shall be conditioned upon compliance with Title 82, chapter 4, parts 1 and 2.
(2) These coal leases are subject to the condition that the coal must be mined, handled, and marketed in a manner that will prevent as far as possible all waste of coal and are also subject to the condition that the mining operations shall be carried on in a systematic and orderly manner that will not make subsequent mining operations more difficult or expensive. A violation of any of these conditions is grounds for the forfeiture of the lease after a hearing before the board.
