综采工作面超前支护技术研究

综采工作面超前支护是影响工作面安全生产的重要方面.以A矿14-1103综采工作面为工程背景,对该工作面超前支承应力规律进行了分析研究,对支护形式进行了对比选择,最终制定了合理的支护方案,并在工作面上下顺槽采用超前液压支架对巷道进行了超前维护.实践表明,该支护方案不仅提高了支护效率,降低了巷道围岩的变形量,保障了工作面的...

Study on Advance Support Technology of Fully Mechanized Mining Face

The advance support is an important aspect that affects the safety production of the working face.Based on the engineering background of the 14-1103 fully mechanized mining face of A mine,this paper studied and analyzed the law of the advance support pressure of the working face,compared and selected the support forms,and finally formulated a reasonable support scheme.The advance hydraulic support was used to maintain the roadway in the upper and lower grooves of the working face.The practice shows that the support scheme not only improves the support efficiency,reduces the deformation of the surrounding rock of the roadway,guarantees the safe production of the working face,but also provides reference for the advanced support of other working faces in the mine.
