1、第一章工程概况磴槽煤矿1#斜井分为上下两段，总工程量为斜长1100m，主要用于上下人员与升降材料和设备，上部表土层及风化基岩段约70~80m将过完，当基岩完整稳定上升至巷道顶板5m后，将改为锚网喷支护，若基岩段施工遇构造带或顶板破碎区，应及时修改支护形式，可采取加打锚索或套U型钢拱形棚子等加强支护。基岩段巷道断面特征如下：S掘=14.8m2，净宽4.4m，净高3.6m，支护材料规格：锚杆采用Φ18Х2200左旋等强螺纹钢树脂锚杆，片网采用Φ6mm冷拔丝钢筋加工，规格3000×1000mm，网格5
2、0×50mm，锚网最小空顶距≯800mm，喷浆空顶距≯两炮进尺。喷浆厚度100mm，喷射砼强度不低于C15。第二章地质情况概述一、地层一#斜井顺着二1煤底板一层7.5——8.5m厚的石灰岩底板掘进，工作面岩性为石灰岩、细沙岩及砂质泥岩。二、煤层及瓦斯设计巷道顶板距二1煤层底板间距为20-60m,二1煤层为采空区，有可能积聚瓦斯或遇构造传导瓦斯，施工中注意瓦斯观测，加强瓦斯监控。三、水文及地层设计巷道顶板为7.5m厚的石灰岩层，再往上12.5m左右时二1煤层的采空区，有可能积水，在施工中会有顶板淋
3、水现象，注意观察石灰岩含水层及老塘水，做到有疑必探，该灰岩含水层产生水力联系时，富水性则会相应增强，为直接冲水含水层。四、构造地层为单斜构造简单不复杂。第三章施工方法一、施工方法当该巷道进入稳定基岩后我们将采取钻爆法，进行光面爆破，全断面一次打眼，分次放炮，采用两掘一喷循环作业，实行“三八”工作制，打眼深度2.1m，全断面可布置76个眼，有效进尺1.9——2.0mmassestour;Increasetheintensityoftheinvestigationandmediationofdisp
