The experimental samples are coal drill cuttings from coal seams in Yunnan Hexing Coal Mine of China. Sieve the original coal drill cuttings to 1~3 mm, and then weigh each coal sample in five different masses (5 g, 10 g, 15 g, 20 g, and 25 g), respectively (Figure 1). Then, the particle size and shape distribution of each sample The large amount of crushed coal powder and gas from coal and gas outbursts demonstrates the instability and damage to weakly bonded coal particles (Fig. 23) under the action of strain energy and gas expansion energy. In the simulated results, crushing energy and friction dissipate most of the boundary work, and elastic energy is Investigation on tectonically deformed coal particle crushing
