Because the direct roof of the No.92 ore-body is the backfilling of the No.91orebody which is the cementing materials or non-cementing materials, and there are no-filled mined-areas in someplace. So there are large-scale hidden troubles on the top of the No.92 slowly inclined large and thick ore-body, then we must find a new mining technology which aims at the complex mining condition of the No.92 ore-body. The cutting nature of the No.92 ore-body is very poor, so choosing the rational drilling and blasting parameters and enhancing the overall technological economic benefits are also the urgent problems waiting to be solved in the exploitation of the No.92 ore-body. The No.92 ore-body, thin lodes and the exploitation process of the No.91orebody influence each other, the geo-pressure phenomena aggravates obviously in case of the mined-areas increase constantly, and the geo-pressure problem will be more and more serious when the No.92 ore-body be exploited on a large scale in the next step.

由于它的直接顶板就是开采91号矿体时的胶结或者非胶结的空区充填体，部分地段甚至是未充填的采空区，使92号缓倾斜厚大矿体的上部形成大范围的隐患区，因此，必须针对92号矿体复杂的开采技术条件，寻找新的采矿技术与工艺。92号矿体的可凿性极差，选择合理的凿岩爆破参数，提高凿岩爆破工作的总体技术经济效益，也是92号矿体开采急待解决的问题。92号矿体与细脉带、91号矿体开采相互影响，目前在采空区不断增大的情况下地压显现有明显加剧的趋势，在下一步92号矿体大规模开采时，地压问题将越来越严重。

Preparing rotary steel cage comprising one rotating frame, one steel cage and one driving mechanism; and 2. setting the rotary steel cage in the tail of haydite calcining rotary kiln and introducing hot tail gas through the cavity channel of the steel cage, rotating the steel cage, loading raw haydite pellet into the steel cage through the upper inlet for drying through contact with hot tail gas, and discharging the stoved haydite pellet through the lower outlet.

一种淤泥陶粒生产的预烘干工艺，其特征在于它包括如下步骤：1准备回转钢笼：回转钢笼由旋转架(1)、钢笼(2)、旋转驱动机构构成；2将回转钢笼置于陶粒煅烧回转窑的尾部，将回转窑通风所产生的热尾气由钢笼(2)低端口导入钢笼(2)的空腔通道中；启动回转钢笼的旋转驱动机，旋转驱动机驱动旋转架(1)旋转，带动钢笼(2)旋转；待预烘干的陶粒生料球从钢笼(2)的高端口进入钢笼(2)的空腔通道中，陶粒生料球在钢笼(2)的空腔通道内翻转时与由钢笼(2)低端口导入的热尾气充分接触，从而迅速烘干水分；烘干后的陶粒生料球从钢笼(2)低端口排出。

First, she tried to look down and make out what she was coming to, but it was too dark to see anything; then she looked at the sides of the well, and noticed that they were filled with cupboards and book-shelves; here and there she saw maps and pictures hung upon pegs. She took down a jar from one of the shelves as she passed; it was labelled 'ORANGE MARMALADE', but to her great disappointment it was empty: she did not like to drop the jar for fear of killing somebody, so managed to put it into one of the cupboards as she fell past it.

但是下面太黑了，什么都看不见，于是，她就看四周的井壁，只见井壁上排满了碗橱和书架，以及挂在钉子上的地图和图画，她从一个架子上拿了一个罐头，罐头上写着&桔子酱&，却是空的，她很失望，她不敢把空罐头扔下去，怕砸着下面的人，因此，在继续往下掉的时候，她就把空罐头放到另一个碗橱里去了。
