Roadway Supporting Technology Influenced by Mining and Protective Pillar Design

For relieving nervous relationship of mining and driving, mining face layout is changed to sequence mining from skip mining. Adjacent mining face is influenced by mining repeatedly. Based on theory research, high-strength and high-rigidity mightiness bolt supporting system can effectively solve the difficult problems of supporting roadway influenced by dynamic mining. This system can decrease supporting density, improve driving speed, reduce labor density, optimize scale of protective pillar and ultimately mine coal resource.
