    Mining Methods Development of Mining Methods. The first method of mining coal from Kansas rocks was a primitive form of strip-mining which may be aptly termed crop-working. Possibly the Indians were the first to employ this method of removing coal from the outcrop by means of crude hand implements.

    A New Theoretical Method To Predict Strata Movement

    Mar 11, 2021 The mining-induced strata movement and surface subsidence are closely related to the dip angle of coal seam. However, most surface subsidence prediction methods are empirical, and only suitable for nearly flat coal seam mining. In this paper, a new theoretical method is proposed to predict the strata movement boundary and surface subsidence caused by inclined coal seam mining,
