22、系到整个矿井的建设、生产和经济效益，为了加快矿井的建设速度、缩短建井周期、保证正常的生产接替和提高矿井产量，经常采用多井口或多头掘进，这样就会出现两井间或井田的长距离巷道贯通测量，所以两井间贯通测量就成为了矿井生产中必不可少的一项工作4。近 50 年来，随着电子技术、计算机技术、光机技术和通讯技术的发展，测绘仪器制造也得到了长足进展，其高科技产品代表之一就是电子全站仪。全站仪是当前比较流行，也比较实用的测绘仪器。应用全站仪与传统的科技手段和地质勘探技术理论相结合，在矿山勘探、设计、开发和生产运营的各个阶段，对矿区地面和地下的空间、资源和环境信息进行采集、存储、处理、显示、利用，将极大地提高资源

23、勘探的效率，降低成本，减少人力物力，使矿区开采更加有效地进行。国际上矿山测量仪器正向着多功能、小型化、数字化和全自动化方向发展。目前国内外两井贯通理论比较成熟，两井间贯通必须遵循以下原则：1. 在确定测量方案和方法时，应保证贯通所必须得精度，过高和过低得精度要求都是不可取得。2. 对完成得测量和计算工作均要有客观得检查，如：进行不少于两次独立测量；计算由两人分别进行或采取不同得方法，不同计算工具等。精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 1 页，共 5 页Delegates, staff: Hello! in the run-up to t

45、发展，相继应运而生了“预裂爆破( 也包括原来的“轮廓线钻孔法) 等爆破方法，这些方法可统称为“光面爆破 。光面爆破 (smooth blasting)是井巷掘进中的一种典型的控制爆破方法，目的是使爆破后留下的井巷围岩形状规整，符合设计要求，表面光滑，损伤小，稳定性强。光面爆破只限于断面周边一层岩石 (主要是顶部和两帮 )，所以又称为轮廓爆破或周边爆破。在井巷掘进中应用光面爆破具有以下优点：(1) 能减少超挖和出岩量，特别是在不稳固岩石中更能显示其优点。(2) 对井巷围岩的炮震扰动范围小，相应的炮震裂缝少；可有效地减少应力集中引起的塌方，减少落石和危险断面，避免事故发生和人员伤亡；改善作业环境，

46、增加施工的安全性，并能减少放炮后的排险时间，提高施工速度，特别是在岩性不良地段，效果更为显著。(3) 巷道轮廓外裂隙范围较小，对围岩强度破坏不大，提高了巷道的稳定性，不需要或很少需要加强支护，减少了支护工作量和材料消耗。(4) 能加快巷道掘进速度，降低成本，保证施工安全。文献来自作者： 陈国良学位授予单位：广西大学三、分析研究的可能性、基本条件及能否取得实质性进展(方案论证 ) 利用国内外各种实际光爆案例额对比是否能在东周窑煤矿的两井贯通工作中引入光面爆破，进行误差分析是否具有可行性。利用光面爆破理论研究的理论基础与历次的实践运用22光面爆破原理光面爆破的实质，是在井巷掘进设计断面的轮廓线上布

47、置间距较小、相互平行的炮眼，控制每个炮眼的装药量，选用低密度和低爆速的炸药，或采用不耦合装药，同时起爆，使炸药的爆炸作用刚好产生炮眼连线上的贯穿裂缝，并沿各炮眼的连线一井巷轮廓线，将岩石崩落下来。目前关于裂缝形成的机理有以下三种观点：(1) 应力波叠加原理在光学材料模型实验中，当相邻两装药同时爆炸时，应力波在两炮孔的连心线方向精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 2 页，共 5 页Delegates, staff: Hello! in the run-up to the Spring Festival, we held one sessi
