Research on the Comprehensive Control Technology about Gas in the Large Mining Height and Extended Mining Face for the High Gas Mine

Advanced Materials Research, 2011
The paper describes the three-tier stereo comprehensive management gas model for the mining height and extended mining face in the high gas mine. The model consists of gas drainage with surface drilling, progressive and shielding gas drainage with 1000m drilling machine from underground and so on. The measures make it easy to realize the combination of

Stability Analysis of Hydraulic Support in Large Inclined and High Mining Height Coalface

Applied Mechanics and Materials, 2011
Under the condition of large inclined angle, the stability control of hydraulic support was always the challenge for the fully-mechanized mining in large inclined coal seams. Based on the specific geological conditions of 509 coalface with large inclined and high mining in Gaozhuang mine, the model of hydraulic support had been drawn by using ...
