锚注与锚索联合支护技术在推采断层中的应用

Anchor and Anchor Rope Combined Support Technology in Injection on the Application of the Mining Fault

巨野煤田某矿1309工作面地质构造复杂,过断层期间直接顶和基本顶的稳定性难于控制,导致工作面煤壁片帮严重,顶板冒落,影响正规循环推采速度。采用锚索支护和注化学浆的锚注支护技术加固煤岩体,增加了围岩体的内聚力和内摩擦角,提高了煤壁和顶板的强度和承载能力,取得了显著的效果。

Juye coal mine 1309 face complex geological structure, fault during the immediate roof and the stability of basic roof is diffi- cult to control, lead to serious, working face of coal wall piece of help, roof caving influence normal circulation mining speed. Using anchor cable and anchor chemical pulp injection coal rock reinforced by supporting technology, increase the cohesion and internal fric- tion Angle of rock, improve the coal wall and roof strength and bearing capacity, and has obtained the remarkable effect.
