1、巷道围岩散热是通风巷道内的主要热源, 它对于矿井风温预测、
制定降温措施和计算掘进工作面的制冷量都是至关重要的. 过去计
算这一部分散热量时, 常常借助于有限差分法和有限单元法, 但这两
种方法运用到半无限体时, 势必要人为地假定外部边界, 使得数学模
型与实际有一定的偏差; 而且在具体操作中, 其求解规模和数据准备
量也较大.本文采用边界单元法, 将区域内部的积分问题转化到边界
上, 然后再以问题的基本解建立边界积分方程, 对时间和边界离散进
行数值计算
Heat dissipation of roadway surrounding rock is the main heat source
of ventilation roadway in it for the mine air temperature prediction,
formulate measures to cool and calculated tunneling working face
refrigerating capacity is very important. In the past this part calculated
heat release, often by means of finite difference method and finite
element method, but the two methods applied to the semi- infinite body, is
bound to artificially assumes that external boundary, makes the
mathematical model and the actual has certain deviation; And, in the
concrete operation of its scale and amount of data preparation is larger.
This paper, by using the boundary element method to convert problem
areas within the integral to boundary, and then to question the basic
solution of boundary integral equation, the numerical calculation was
carried out on the discrete time and boundary
2、治理采空区火灾工作要求对采空区遗煤氧化规律有全面的认识!
目前研究者普遍认为工作面推进速度 ，遗煤的厚度和粒度，采空区漏
风情况以及遗煤自身的自燃特性影响着采空区的自然发火的进度，然而，采空区遗煤的自燃是一个非常复杂的物理化学变化过程，也是一
个多变的自动加速放热过程!微 观上煤的自燃过程就是一个煤表面分
子与氧不断地复合不停地发生各种氧化反应，连续释放出反应热的过
程!当采空区其他条件相同时，如果遗煤的粒度不同，则采空区遗煤
表现出来的氧化升温速度就 不可能相同!因为煤的粒度不同，孔隙率
不同会导致煤的表面积不同，跟氧气结合的表面活性结构的数量 就不
同最后致使煤的氧化速度不一致!本文以煤氧复合理论为基础，通过
几种粒径煤的氧化升温 实验，尝试找出遗煤粒度对氧化速度的影响规
律!
Governance goaf fire work requirements of traces of goaf coal oxidation
laws have a comprehensive understanding of! Now researchers widely
believe that working face advancing speed, but the thickness of the coal
and granularity, goaf air leakage and heritage of coal spontaneous
combustion characteristics of its own influence the goaf spontaneous
combustion progress, however, traces of goaf coal spontaneous
combustion is a very complex physical and chemical change process, is
also a changeful heat release process in automatic! On microscopic coal
spontaneous combustion process is a coal surface molecules and oxygen
compound kept constantly produces various oxidation reaction,
continuous release heat of reaction process. Traces of other conditions for
the mined-out area at the same time, if the coal particle size is different,
the traces of mined-out area of coal oxidation heating speed can not be
the same! Because of coal particle size, porosity different will lead to the
surface area of coal, with the amount of oxygen combined with structure
of the surface activity of different final speed of coal oxidation
inconsistent! In this paper, based on the theory of coal and oxygen
compound, by raising the temperature of several kinds of particle size of
coal oxidation experiment, trying to find out the influence law of coal
particle size on the oxidation rate of kin!
