三山岛金矿新立矿区西南翼海底破碎巷道支护应用技术研究

Sanshandao Xinli mine southwest wing submarine Broken Roadway Support Technology Research and Application

三山岛金矿新立矿区西南部119#~159#勘探线-165m水平是新发现矿体,其厚度14~45m,倾角60~75°,局部有直立倒转现象。矿体稳固性差,矿岩破碎,断层节理发育,矿体上下盘均为破碎带,主要井巷工程难以形成,矿体局部存在泥化现象,开拓采准难以进行。且矿体向深海延伸,安全风险更大,因此对此类型巷道进行支护研究,对保障三级矿量和矿山均衡发展具有举足轻重的意义。

Sanshandao gold mine new qualification of Southwest 119#~159# exploration line-165 m is newly found orebody and the thickness of 14~45m, angle of 60 to 75 degrees, local have erect reversal phenomenon. Orebody solid poor broken orebody. The ore body exists in the local argillization. Development of mining difficult. And the ore body extends to the deep sea, has the vital significance to the safeguard three level mine quantity and the mine balanced development.
