1) thick coal zones
厚煤带
2) thin-thicrness-changed coal band
煤厚变薄带
3) no coal zone
煤厚削减带
1.
This is so called no coal zone.
针对辽宁省康平县小康煤矿投产以来，在掘进和回采生产工作中，多次遇到煤层削减变薄甚至完全尖灭的现象，即煤厚削减带(煤矿曾称之为“无煤带”)。
4) coal thickness
煤厚
1.
Based on ArcGIS coal thickness spatial distribution forecast method research;
基于ArcGIS的煤厚空间分布预测方法研究
2.
Structural analysis of half variation function of coal thickness;
煤厚半变差函数的结构分析
3.
With the cartography of the isoline chart of coal thickness and other analyzing chart,the changing law of coal thickness was discussed,and the influenced factors for coal thickness changing were analyzed.
通过制作二1煤层厚度等值线图及其它分析图件,对煤层厚度变化规律进行了一些探讨,对影响煤厚变化的原因进行了分析。
6) Thickness of coalbed
煤厚
1.
The main factors affecting thickness of coalbed is depositional environments.
研究结果表明，煤层主要分布在该组下段的中下部，厚煤带呈ＮＥＥ展布，煤厚与煤系厚度及砂体厚度有关，沉积环境是引起煤厚变化的主要因素，可采煤层主要形成于废弃三角洲平原上。
