16、板等高线,本巷道位于B2煤层顶板岩层中,距离最近岩柱31m,最远68米。巷道顶底板位于粉砂岩中。3、 预测巷道瓦斯涌出量、突出倾向: (一)预测中央水仓及沉淀池掘进工作面的瓦斯绝对涌出量按0.1 m/mim计算。(二)本巷道是在B2煤层顶板岩层中掘进,与B2煤层之间最近岩柱31米,因此没有突出危险。四、地温、地压:施工区域在-800m,为二级高温区。地压正常,无冲击地压。第三节 地质构造根据三维地震勘探提供的B2煤层底板等高线图,和在-800井底车场探B2煤结果,巷道掘进过程中预计无断层。第四节 水文地质 一、根据-副井井底车场及北部运输大巷掘进过程中揭露,本巷道将要穿过的粉砂岩、泥岩,该层粉
17、砂岩竖向裂隙发育,局部裂隙含水,在巷道掘进到裂隙发育地段时,顶板还有可能出现淋水,预计最大涌水量为1mh,一般0.5-1mh左右,补给关系主要是上层含水层渗入,不会为施工造成威胁。二、根据资料及实际揭露,笨巷道施工区域没有老巷、老空积水,没有钻孔和构造导水,不会给施工造成威胁。附图2-1:岩(煤)层综合柱状图附图2-2:-800m水平中央水仓及沉淀池预想地质剖面图 第三章 巷道布置及支护说明第一节 巷道布置-800m水平中央水仓及沉淀池位于主井井筒以北,设计长度618.916m。其中包过内外水仓交岔点。 1、-800水平中央水仓通道自井底车场八号交岔点牛鼻子西2米处,按照1-1断面、31728
