    • 摘要: 曾经在《当代教育家》杂志读到李振村老师写的《等压教育》这篇文章,困扰我多年的一个疑团解开了。在学校里有这样一类怪现象:一个特别严厉的班主任,班里的孩子因为很怕他,所以上班主任的课时显得专心致志,在老师面前也表现得规规矩矩。可一轮到其他老师来上课,就会"原形毕露",说笑打闹,放松得不得了;再或者学年结束,另换了一个比较温柔的班主任,按理说大家更能"和平相处",可是这个班的学生居然会闹翻天。

    • 摘要: In order to change the phenomenon of mining tension after the implementation of permeability improvement measures for low permeability coal seam,inspired by the oil displacement by imbibition mechanism of oil and gas reservoirs in the field of oil and gas reservoir mining,by building the experimental platform,under the constant pressure of the experimental system,the study on the effect of imbibition was conducted.The experimental results show that after water enters the coal,adsorption of gas in coal can he replaced to promot gas desorption;both the maximum amount and rate of imbibition have a positive correlation with water content.However,the difference between the adjacent points decreases with the increase of water content.In the initial stage,the speed increases quickly.Combined with the experimental study,a new method of using imbibition effect as supplementary measure to promote gas drainage in the late period is proposed.%针对低渗煤层增透措施后仍存在采掘紧张的情况,启发于油气藏开采领域渗吸驱油机理,通过搭建实验平台,在实验系统压力恒定条件下研究了外加水分对煤中瓦斯的渗吸效应.实验结果表明:水分进入煤体后,能够置换出煤中吸附瓦斯,促进吸附瓦斯解吸;最大渗吸量和渗吸率与含水率正相关,但相邻点的差值随着含水率的增加逐渐减少;渗吸初始阶段,渗吸速度增长快.为改善上述情况,结合实验研究,提出1种在瓦斯抽采后期利用渗吸作用作为补充措施的促抽方式.

    • 摘要: 主要论述理想气体分别在等温等压下反应和在等温等容下反应的标准平衡常数K(○)分别选择不同浓标P(○),C(○)时四种不同标准平衡常数对温度变化响应的差异性,由此看出K(○)c的特殊性.进行了严密的理论推导,并深入分析了造成这种差异的原因.并对四种不同标准平衡常数在过渡态理论的应用中得出的四种活化能和四种速率常数长期以来的错误进行了纠正.%In this article, it is strictly deduced that four different kinds of standard equilibrium con-stants K -of ideal gas reactions show different response to change of temperature for the difference between concentration scale P(○) and C(○) with isobaric or isochoric reaction condition. The theoretical reason of the difference is analyzed thoroughly. And the error of application of four different kinds of standard equilibrium constants that has existed for a long time is corrected with four different kinds of rate constants and activation energy in transition state theory.

    • 摘要: 针对目前实验室研究含瓦斯煤渗吸效应的缺陷,搭建等压实验平台,在实验系统压力恒定条件下,对不同水分自然流入含瓦斯煤后的渗吸效应进行测试,并与非恒压条件下含瓦斯煤渗吸效应进行对比.结果表明:随着含水率的增加,渗吸量逐渐增大到稳定的数值,但渗吸量的增加幅度逐渐变小;渗吸速度包括快速增加、缓慢持久、衰减至0 3个阶段;等压条件下比非等压条件下的渗吸量和渗吸率高.%Aiming at the shortcomings of the present laboratory research on imbibition effect of coal containing gas,the experimental platform was set up under the condition of constant pressure.Under constant pressure of the experimental system,imbibition effect of coal containing gas with natural water flow was tested compared with the non constant pressure.Results show that with the increase of moisture content,the amount of imbibition gradually increases to a stable value,but the amplitude of variation becomes smaller;the speed of imbibition is divided into three stages,including rapid increase,slow persistence,and decay to zero;the amount and rate of imbibition under the condition of constant pressure are higher than that under non constant pressure.

    • 摘要: 神东矿区综采末采使用辅巷多通道回撤技术,通过对末采阶段和支架回撤阶段矿压显现规律的研究,提出了末采等压的顶板控制技术.以补连塔煤矿22303综采工作面为例,研究得出:在综采工作面末采贯通前需通过计算留预留一定尺寸的等压煤柱进行停采让压,当工作面来压后基本顶回转断裂,形成稳定砌体梁结构,在贯通时主回撤通道将不会来压,能够保证支架的安全回撤;当让压后工作面仍不来压,则工作面在回撤时将处于来压状态,需要加强回撤通道的支护强度,防止压架事故发生.%End-mining of fully mechanized coal mining in Shendong Mining Area uses auxiliary lane multi-channel retraction technology.Through the research of strata behaviors laws in end mining stage and support retraction stage,the paper proposes end-mining isobaric pressure roof control technology.This paper takes 22303 fully mechanized coal mining face in Bulianta Coal Mine as an example.Studies show that a certain size of isobaric coal pillar needs to be reserved by calculation to stop mining and yielding before the interconnection of fully mechanized mining face end mining.Basic roof is fracture and turns to form stable masonry beam structure when the working face is pressed;the main retraction channel will not be pressed during the connection period,which can ensure the safety of support retreat.If the working face is still without pressure after yielding,the working face is in a state of pressure during the retraction period;it needs to strengthen the support of withdrawal channel to prevent the accident of supports crushing.
