为了研究复杂地质条件下综采工作面旋采技术,以某矿12124综采工作面为工程背景,采用虚心旋采方法,调斜比例设计为1∶3,带式输送机进行转弯改造,进行了复杂地质条件下旋采角度为18°、旋转距离为22.608 m的工业试验。在旋采过程中对巷道和工作面矿压进行监测,旋采效果令人满意。
In order to study the technology of rotary mining in fully mechanized coal mining face with complex geological conditions, taking 12124 fully mechanized mining face of a mine as the engineering background, adopting the method of open-hearted rotary mining, the ratio of inclined-inclined design is 1: 3, the belt conveyor is modified by turning Under the complex geological conditions, the extraction angle of 18 °, the rotation distance of 22.608 m industrial test. During the process of rotary mining, the pressure of roadway and working face is monitored, and the result of rotary mining is satisfactory.
