Based on the field investigation and the statistical data obtained from Xuzhou, Datung and other coal mines, analysis of the technological process and system reliability of the active working face, in conjunction with the correlated analysis of the unit face productivity vs. face length, has been presented in this paper. The economic-mathematical simulation with computer has also been established. Thence, the paper presents an exponential interrelated expression including the parameters of wall advance and face length, provides a means to evaluate the all-over mining efficiency of a fully mechanized face, and develops a comprehensive method to optimize the face length for fully-mechanized longwall coal mining.

本文以徐州、大同等矿的实际测定和统计资料为依据,通过对综采工作面生产工艺和系统可靠性的分析,工作面单产和面长的相关分析,典型条件的经济数学模拟和计算机模拟,提出了工作面进度与面长的指数关系表达式,综采面采煤综合有效系数的确定及综合进行综采工作面长度优化的方法。

In synthetical optimization, of the main parameter of the coal working area, the reasonable face length ιdepends mainly on the interrelated formula V0 = f(ι), where V0 is the face advance. Eased on the analysis of an economic-mathematical model of optimization and the variation of the face advance, this paper presents a practical formula and method for the discrimination of the reasonable face length. Some examples of optimization are covered and a standard value for discrimination is recommended....

In synthetical optimization, of the main parameter of the coal working area, the reasonable face length ιdepends mainly on the interrelated formula V0 = f(ι), where V0 is the face advance. Eased on the analysis of an economic-mathematical model of optimization and the variation of the face advance, this paper presents a practical formula and method for the discrimination of the reasonable face length. Some examples of optimization are covered and a standard value for discrimination is recommended. In usual case, it is pertinent to increase the face length when the increase of working area is over 5% for a face length increment of 20m.

在采区主要参数综合优化中,合理的回采工作面长度主要受工作面推进度V_0与工作面长度l之间关系V_0=f(l)的影响。通过对优化经济数学模型的分折,根据推进度的变化,论证了判别合理工作面长度的表达式和实用方法。归纳了一些优化实例,推荐了在判别中所用的标准值。一般情况下,如果工作面长度每增加20米,回采面积的增加大于5%,加大工作面长度是合适的。
