随着矿井开采深度及采掘强度增大、开采集约化程度越来越高,瓦斯灾害严重程度不断增加,高瓦斯矿井煤巷掘进过程中瓦斯治理问题成为制约矿井安全高效生产的主要因素。同时由于井田面积大,不同区域瓦斯赋存、地质构造情况变化差异较大,掘进面采取固定的瓦斯治理方法严重影响矿井的采掘接替。本文通过收集整理现场高瓦斯矿井掘进工作面煤巷瓦斯治理方法,经过充分论证后提出了高瓦斯矿井煤巷掘进工作面瓦斯分级治理方法,针对不同瓦斯灾害等级采取不同的瓦斯治理措施,并为井下掘进巷道的安全、高效作业提供技术保障。

作者： Zhao zhencai and Chen BingThe Second Crustal Deformation Monitoring Center,SSB,Xi’an 710054,China

Based on the arrangement of the across-fault measurement data along the northern edge of the Qinghai-Xizang block,we divide the deformation into different types and probe the nature of various fault movements based on these *** recent situation of tectonic movement of main structural belts and seismicity in this area are *** the above,it is concluded that across-fault measurement can reflect not only the conditions of fault movement nearby but also the change of regional stress fields; not only is this a method to obtain regional seismogenic information and to conduct short-term prediction but it is also involved with large scale space-time prediction of moderate and strong earthquakes on the basis of the macro characteristics of fractures.

Objective: Study the influence of the stop time in winter, times of plateau on the index in early days for plateau constructors meet;Method:Is it participate in plateau construction of 2002-2004 to choose,enter into the plateau again of 2003-2005 practise clothes finish to mate 326 materials “physical examination in front of the worker",which is passed in Nanshankou Hospital in early days, divided into 3 groups according to the difference of year for the physical examination, examine by leaning towards relevant analytical methods;Result: （1） In the situation of day controlling about the stop time in winter, times of garrison in plateau and blood and oxygen saturation lever （SaO2）, the systolic pressure （sBP） is presented and shouldered relevantly winter to control. Present positive correlation with the value of hemoglobin （Hb）;（2） It is stopped that in case of controlling and is garrisoned in the number of times of plateau in winter day and blood and oxygen saturation lever （SaO2） to present positive correlation. Present and shoulder with the hemoglobin （Hb） ***: In order to ensure the health of plateau constructors to the maximum extent, should try one’s best to reduce the number of times of returning to the plateau in possible cases. At the same time each one constructs for year and returns to the time that the hinterland concentrates rest should be on above 90 days.

High altitude deadaptation affects the health of population returned to the plain. We examined major physiological functions in 348 healthy control subjects and 626 Qinghai-Tibet railway construction workers who returned to the plain from the Qinghai-Tibet plateau. Blood indices, such as hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin concentration and platelet larger cell ratio, of the returned group that had stayed at high altitude more than 3 years were significantly higher than those of the control group. Red blood cell distribution width and platelet were significantly lower in the returned group than in the control group. Compared to the control group, five years after returning to the plain, the returned group had higher mean corpuscular hemoglobin and lower red blood cell distribution width. Detection rate of hypotension and low pulse pressure were significantly higher in the returned group than in the control group at 20 months after the return, and cardiothoracic ratio was significantly higher in the returned group than in the control group at 40 months after the return. Short-term memory function was significantly lower in the returned group than in the control group. Total triiodothyronine and thyroid-stimulating hormone were significantly lower, but total thyroxine and free triiodothyronine were significantly higher in the returned group than in the control group. Sex hormones level returned to normal level in the returned group. Superoxide dismutase was significantly higher and malondialdehyde was significantly lower in the returned group than in the control group. Fatty acid binding protein was significantly higher in the returned group than in the control group, and this difference maintained with time after the return. We conclude that physiological functions of most organs in returned population after exposed to high altitude can not be completely restored to the normal level in a short period of time.

针对柔性罐道工况下双绳缠绕式煤矿深井提升系统运行过程中容器倾斜问题,提出了容器位姿调平控制方法。首先,分析了双绳缠绕式深井提升系统的组成及各组成部分的几何关系,考虑提升系统和浮动天轮液压系统非线性问题,建立双绳缠绕式深井提升系统容器位姿调平非线性控制模型;其次,由于煤矿深井提升环境恶劣,因此提升系统容器位姿反馈信号通过无线装置进行采集,考虑提升系统运行过程中控制量在钢丝绳中传递存在的不确定延时问题,构建了容器位姿调平主动控制矩阵模型,设计了控制信号传输延时补偿观测器,证明了包含延时补偿观测器的容器位姿调平主动控制模型的稳定性;然后,设计滑模控制器实现提升系统容器位姿调平控制,考虑到控制器设计过程中需要容器角度的微分信号,利用高增益观测器为滑模控制器提供光滑的角度微分信号,进而提高控制性能;最后,利用双绳缠绕式煤矿深井提升试验台对提出控制信号延时补偿观测器及容器位姿调平控制方法开展了实验验证,实验结果表明,反步和本文提出的控制器相对于PI控制器具有更优越的响应速度,而提出的控制算法由于添加了延时补偿观测器和高增益观测器,具有更好的控制效果,可以减小容器倾角的峰值与均值,保证双绳缠绕式煤矿深井提升系统的安全运行。
