我坑(尸专)狮山矿体,系似层状沉积变质型矿床。矿岩松散破碎,矿体急倾斜(60°以上),厚2～40米,赋存于黑色和灰白色泥质白云岩中。上盘为专灰色白云岩,下盘为板岩白云岩,矿体长700～1000米。埋(艹上)垂深600余米。矿岩含游离二氧化硅平均在11.37～16.8%左右。矿床采用平窿—竖井—淄井联合开拓。五中段以下,增加一条作为主要出矿用的箕斗井。每50米垂高布置一个中段,采用环形运输。五中段为主平窿出矿水平,在这以上的每个中段均有南、中、北三个窿口,以下为盲中段。所有出矿淄井,人行井、材料井、入风井均布置在矿体上盘,回风辺和8～10个回风井布置在
I pit (corpse) Shishan ore body, similar stratified sedimentary metamorphic deposits. The ore is loose and broken, and the ore body is steeply inclined (over 60 °) with a thickness of 2 to 40 meters and occurs in black and off-white muddy dolomite. On the plate for the special gray dolomite, the next plate slate dolomite, ore body 700 to 1,000 meters long. Buried (艹 on) down more than 600 meters. Ore contains free silica average about 11.37 ~ 16.8%. Deposits using the hole - shaft - Zibo joint development. Five below the middle, add one as a major out of the bucket with the mine shaft. Arrange a mid-section every 50 meters and use a roundabout. In the middle of the main flat hole ore level, in each of these above have South, North and Central, three holes, the following for the blind middle. All out of ore Zijing, pedestrian wells, material wells, into the air shaft are arranged in the ore body plate, return 辺 and 8 to 10 return air wells are arranged in
