煤矿安全隐患闭合管理的研究

分析了现有煤矿安全隐患闭合管理中存在的问题,提出了煤矿安全隐患闭合管理信息化的解决方案。该方案将煤矿安全隐患的闭合处理和安全巡检人员的工作有机地整合在一起,并使用井下手持设备来完成煤矿安全隐患的闭合管理,规定了安全巡检人员按时、按地点的进行巡检,对安全巡检人员的工作进行有效的监督,杜绝了空班漏检等各种违规现象的发生。     

Optimal measurement configurations for kinematic calibration of six-DOF serial robot

An optimal measurement pose number searching method was designed to improve the pose selection method. Several optimal robot measurement configurations were added to an initial pre-selected optimal configuration set to establish a new configuration set for robot calibration one by one. The root mean squares (RMS) of the errors of each end-effector poses after being calibrated by these configuration sets were calculated. The optimal number of the configuration set corresponding to the least RMS of pose error was then obtained. Calibration based on those poses selected by this algorithm can get higher end-effector accuracy, meanwhile consumes less time. An optimal pose set including optimal 25 measurement configurations is found during the simulation. Tracking errors after calibration by using these poses are 1.54, 1.61 and 0.86 mm, and better than those before calibration which are 7.79, 7.62 and 8.29 mm, even better than those calibrated by the random method which are 2.22, 2.35 and 1.69 mm in directions X, Y and Z, respectively.

云南省弥勒县宝园铜矿成矿条件分析

弥勒县宝园铜矿区在大地构造上主要处于扬子准地台滇东台褶带,区域构造基本形态为一地堑构造。区内矿床多以铜多金属矿为主,大部分发育于近地表喷发的玄武岩熔岩层序中,部分产在玄武质角砾岩中,玄武岩长期遭受风化淋滤,可次生富集,在岩溶盆地、溶蚀凹地及张性断裂等有利部位形成铁、铜矿。本文通过分析,认为该区成矿条件十分利于富集成矿。     

云南省蒙自县老寨街银多金属矿区找矿远景分析

老寨街矿区地处滇东南钨锡多金属成矿带,其外围已发现了多个铜、锌、银等多金属矿床。通过分析矿区的成矿背景及地质特征,对比周边矿床的成矿条件,结合以往的化探成果,对该区的成矿优势进行了分析总结。初步认为该区具备形成铜、锌、银矿床的基本条件,成矿及找矿前景极为优越,并圈定了三个找矿远景区。
