突出煤层沿空掘巷有效保护范围考察
Investigation of Effective Protection Area of Gob-side Entry Driving in Outburst Coal Seam
-
摘要: 在突出煤层沿空掘巷时,确定卸压煤层区域有效保护范围、保证巷道在无突出危险区安全掘进至关重要。通过理论计算和残存瓦斯含量考察相结合的方法确定了沿空掘巷的有效保护范围,并通过跟踪考察煤巷掘进期间的突出预测指标和瓦斯涌出量数据进行了验证,确保了区域划分的可靠性、准确性,保证了巷道安全、快速掘进。Abstract: It is very important to determine the effective protection range of coal seam and ensure the safe driving of roadway in no outburst danger zone during the gob-side entry driving of outburst seam. The effective protection range of gob-side entry driving in the roadway is determined by the combination mean of theoretical calculation and residual gas content, and the outburst prediction indexes and gas emission data during the period of tunneling are verified by tracking, which ensures the reliability and accuracy of regional division and the safe and fast tunneling.
