    Griffin Coal Geological Modeling And Resource

    Griffin’s coal resources are located in two separate areas of the basin: Ewington in the north and Muja/Buckingham in the south. Resources are contained in the Permian-aged Collie Group, consisting of five formations, three of which are coal-bearing. The oldest of these coal-bearing sequences is the Ewington Coal Measures, followed by the Premier Coal Measures, with the younger Muja Coal

    Enhanced Plant Restoration in Open-Pit Mines Using

    Though plant restoration has been regarded as an efficient way, its application is often restricted by the physicochemical properties of the soil, i.e., macronutrient deficiencies. In this work, a novel plant restoration method was proposed that employs maize straw and ultrasonically pre-treated coal fly ash (UCFA) for soil amelioration. Seed germination experiments were performed to

    Natural regeneration on land degraded by coal mining in a

    Such studies would assist in informing ecological restoration of these degraded sites. Here, a chronosequence approach was used to investigate early‐stage primary succession on overburden spoil wastes derived from coal mining in a tropical climate over a 64‐month period. Plant species composition and several microclimatic and spoil physicochemical and microbial properties were measured
