摘要
为保证综放工作面的安全高效生产,应用了高低压深孔超前注水技术。通过介绍煤层高低压深孔注水机理,详细分析高低压深孔注水在"豫西三软煤层"中对瓦斯抽采、应力集中区弱化、瓦斯释放和煤层防治等方面的实际应用效果,并提出该技术的实际推广意义,为综采工作面的安全高效生产奠定了良好基础。
In order to ensure the safe and efficient production of fully mechanized top coal caving face,high and low pressure deep hole advanced water injection technology is applied.By introducing the mechanism of high and low pressure deep hole water injection in coal seam,this paper analyzes in detail the practical application effect of high and low pressure deep hole water injection on gas drainage,weakening of stress concentration area,gas release and coal seam prevention in“three soft coal seams in western Henan”,and puts forward the practical popularization significance of this technology,which lays a good foundation for the safe and efficient production in fully mechanized mining face.
