摘　　要：中国的煤矿瓦斯安全形势严峻,许多矿井建立了井下瓦斯抽放系统。但是瓦斯抽放方案设计没有科学的理论依据是目前存在的主要问题之一。本文从数值模拟的角度提出了建立井下瓦斯抽放数值模型的初步方案,即将边界条件等效和模拟时间前推。这样可以借助国际上成熟的煤储层模拟系统来评价和优化井下瓦斯抽放的方案设计。The situation of gas-related safety is becoming increasingly worse in coal mines in China although many of them have installed various gas drainage systems. One of the major problems is that the designed gas drainage schemes have no scientific theon basis. The author makes the proposal of establishing a preliminary underground gas dra/nage numerical model, which is the equivalent of boundary conditions and shift forward of initial conditions. The design of gas drainage schemes can therefore be optimized through the mature modeling system.
