针对淮南矿区深部复杂地质条件，采用高预应力、强力锚杆支护及锚杆和锚索联合支护技术，可实现一次支护有效控制围岩变形与破坏，特别是锚杆全长锚固支护技术成功应用，解决了软岩、复合顶板巷道的支护技术问题，能更好地发挥岩层与锚杆杆体共同抗剪切作用，抑制围岩离层与错动，充分发挥锚固岩体的自承能力。初步解决了深井高地压复杂地质条件下的巷道快速掘进、快速支护技术难题，从支护效果、支护成本、减轻工人劳动强度，为实现高产高效矿井和工作面创造了条件。

For Huainan mining area deep and complex geological conditions ,the mine can realize a sup-port to effectively control surrounding rock deformation and destruction by high pretensioned stress , strength bolting support and bolt and anchor combined support technology ,especially the total length of anchor rod support technology was applied successfully. That methods solve the problems of soft rock ,the compound roof of roadway supporting technology ,can play a better effect of rock and bolt joint shear ,inhibit the rock separation and dislocation ,give full play to self bearing capacity of the an-chorage rock. The problems of rapid excavation and rapid support technology in deep well under com-plicated geological conditions was solved firstly.Besides ,the conditions for the production of high yield and high efficiency of the mine and the working surface are created.
