摘要
百矿集团针对广西地区软岩巷道进行沿空留巷支护技术探索,针对软岩巷道沿空留巷围岩应力分布及变形特点提出联合支护技术。在那荷煤矿C202轨道巷进行了沿空留巷联合支护试验,证明联合支护技术可有效减少沿空留巷巷道围岩变形,在软岩条件下具有一定的可行性和实用性。
The support technique of retaining gob side entry for soft rock roadway in Guangxi area was expiored by Baise Mining Group Co. , Ltd. A combined support technology was put forward according to stress distribution and deformation characteristics of surrounding rock in retaining gob side entry of soft rock roadway. The combined support test of gob side entry had been carried out in the C202 track entry of Nahe Mine. It was proved that the combined support technique can effectively reduce the deformation of the surrounding rock of retaining gob side entry and had certain feasibility and practicability under the condition of soft rock.
