我矿在推广吊罐法掘进天井的过程中,遇到了装岩机不足的困难。我们坚持以路线为纲,依靠广大工人,大搞技术革新,试验成功漏斗式吊罐天井,解决了装岩机不足和出碴安全的问题,而且提高了出碴效率。根据2个天井的实际资料,每班2～3次循环,作业21个班,总进尺52.6米,平均班进尺2.5米,掌子面平均工班效率1号井0.35米/工班,2号井0.62米/工班。(一)结构形式漏斗式吊罐天井由棚盖、金属翻板、吊杆无腿漏斗三部分组成(图1)。漏斗用来放碴,漏斗上面的金属翻板使罐能够上下通过。金属翻板用4毫米铁板制成,上面焊5根钢轨来加固。
In the process of popularizing the hanging jar method to excavate the patio, the mine encountered difficulties in installing the rock loader. We adhere to the line as the key link, relying on the majority of workers, engage in technological innovation, successful trial funnel-type hanging cans to solve the problem of rock loader inadequate and ballast safety, but also improve the efficiency of ballast. According to the actual data of two patios, each class has 2 ~ 3 cycles of 21 classes with a total footage of 52.6 meters and an average class size of 2.5 meters. Well 0.62 m / working class. (A) Structure Funnel-type hanging tank patio by the cover, metal flap, boom legless funnel composed of three parts (Figure 1). The funnel is used for ballasting. The metal flap above the hopper allows the tank to pass up and down. Metal flap made of 4 mm iron plate, the above welded 5 rails to reinforce.
