<p>A high efficiency mining machine for percussing falling materials without trapping materials. A machine body of the mining machine is provided with a falling material percussion mechanism (3). The falling material percussion mechanism (3) comprises an outer layer material percussion mechanism (4) and an inner layer material percussion mechanism (5). The outer layer material percussion mechanism (4) comprises outer layer material percussion teeth (4.1). The outer layer material percussion teeth are disposed so that materials percussed down by the inner layer material percussion mechanism flow out through gaps between the outer layer material percussion teeth and/or a discharge hole (8) is reserved in the outer layer material percussion mechanism so that materials percussed down by the inner layer material percussion mechanism flow out through the discharge hole (8) of the outer layer material percussion mechanism. The inner layer material percussion mechanism comprises inner layer material percussion teeth (5.1). The inner layer material percussion mechanism and the outer layer material percussion mechanism work with each other to implement percussion and discharge of falling materials. Also disclosed is a high efficiency mining method for percussing falling materials without trapping materials. The mining machine has a simple structure and works in a reliable way.</p> |
