Application of Short-wall Mechanized Mining Technology in Residual Coal Pillar Recovery of Small Mine

Aiming at the recovery situation of residual coal pillar at 29213 gob area in Pingshuo Anjialing No. 2 Mine, from the aspects of roadway layout, layout equipments, mining technology, ventilation at working face, roof management, we introduce the application of short-wall mechanized mining technology by continuous miner. The practice showed that short-wall mechanized mining technology by continuous miner had the characteristics of high degree of mechanization, high adaptability, and good safety. The successful application of this technique for residual coal pillar mining in modernization large coal mine provides a feasible technical solution for improving the recovery rate of coal resources and increasing the economic benefit of enterprises.
