Introduction
Closure of gate roads with soft floor is a problem encountered in the carboniferous coal measures of the North America and Europe. Parameters influencing the stability and performance of the gate roads are numerous. They are often directly or indirectly inter-
related. The most important of these are:
(a) Depth of cover and varying strata pressure.
(b) Dimensions and shape of the gate roads.
(c) Method of the gate road support and its size.
(d) Direction of the roadway advancement relative to the dip of the seam.
(e) Rate of advance.
(f) Geological factors, such as stratigraphy, discontinuities, cementation between the discontinuities, washouts and existence of the tectonic actions.
(g) Type of the roadside packs, its dimensions and behaviour as a support.
(h) Barrier pillar, its dimensions and behaviour.
(i) Panel width or the face length.
(j) Extracted height of the seam.
(k) Proximity of any mining activit

导言
关闭大门的道路软底是一个问题中遇到的石炭纪煤系的北美和欧洲市场。参数影响稳定性和性能的大门道路是多方面的。他们往往是直接或间接地间
有关。其中最重要的是：
（一）深度的覆盖面和不同阶层的压力。
（二）尺寸和形状的大门道路。
（三）方法大门道路的支持和它的大小。
（四）方向发展相对巷道倾角煤层。
（五）推进率。
（ F ）的地质因素，例如地层，不连贯性，胶结之间的不连贯性，冲刷和存在的构造行动。
（ g ）项类型的路边包，它的规模和行为的支持。
（高）壁垒支柱，它的规模和行为。
（一）小组宽度或面对长度。
（ j ）条摘自高度煤层。
（金）接近任何采矿活动的大门道路。
（ 1 ）方法巷道发展和生产技术。
（米）摇滚/支持互动性。
（ n ）非均匀应力分布的支持系统。
（海外）承载力巷道发言。
（规划）类型和质量的支持或加强利用沿公路和背后的脸。
（ q ）支持间隔沿线的道路。
（注册商标）影响水在地板上的材料。
（县）物理，机械和时间依赖行为的岩石巷道周围。
（吨）影响任何抓取或dinting对邻国的支持，即支柱，包装和钢拱。
（ ü ）的立场道路相对faceline及其的前进方向（或后退）例如：先进的标题，后面面对符合抓取嘴唇，或罚款的脸。
评估所有上述提到的参数是一个健全的前提预测，规划和地面控制沿门的道路。已多次尝试的基础上，理论分析和假设的环形道路，以评估上述指出参数[ 1-3 ] 。然而，这些成果，尽管有用，请不要关闭适合就地性能拱形大门的道路断面。
