摘要:
文中以刘河矿13031炮采工作面为实验工作面,采用现场实测和数值模拟的方法研究了复杂地质条件下炮采工作面的超前支承压力影响范围以及强度,为该条件下工作面的超前支护范围和强度提供依据。研究表明:超前支承压力峰值位置为工作面前方10 m,峰值强度为20 MPa,超前支承压力影响范围为工作面前方0~50 m,其中剧烈影响区域为工作面前方0~23 m.
Abstract:
In this paper,Liu-River mine’s 130130 blasting mining face is acted as experiment.To provide a basis for impacted scope and intensing of advancing abutment pressure under the same conditions,we use field measurement and numerical simulation to study it under complicated geological conditions.The study shows that:The peak position of advancing abutment pressure lies 10 meters ahead of face,peak intensity is 20 MPa,the scope of advancing abutment pressure is between 0 to 50 meters ahead of face,and the violent effect region is between 0 to 23.
