Study and Application of Thin Seam Mining Technology and Complete Equipment
QI He-gang
Abstract：In order to realize a safety,high efficient,less personnel or unmanned mining in thin seam,according to the poor thin seam min-ing equipment level and low energy efficiency status,a systematic study was conducted from the thin seam mining technique,complete equipment and other aspects.The thin seam mining technology plan was provided and was applied to the practices.With the gateway height reduced and the coal mining face widened and lengthened,the thin seam mining technique was optimized.The roof cutting,pressure re-leased and gateway retained technology was studied and applied to realize a pillarless mining.The new coal mine automation equipment was researched,developed and applied,the nationalization of thin seam mining equipment was realized.The practice application of thin seam mining technology and complete equipment showed that the complete equipment was high in reliability,the mining face was optimized,the thin seam mining technique was scientific in sequence,the personnel worked in the thin seam mining face were reduced over 2/ 3 and safe-ty and high efficient thin seam mining was realized.
