江西丰城矿区尚庄煤矿B4煤层瓦斯地质规律研究 摘要 瓦斯是煤在地质历史演化过程中形成的气体地质体。瓦斯作为气体，既有它自身的物理、化学属性，又由于它生于煤层、储存于煤层，所以受着地质演化历史的控制。不同含煤地层、不同煤层都存在着自身的瓦斯地质规律。揭示了瓦斯地质规律，也就揭示了瓦斯赋存分布的分区、分带规律等，也就揭示了瓦斯致灾机理。尚庄煤业位于江西省丰城市西北的尚庄街道办境内，距丰城市八公里，距省会城市南昌60公里。矿内有铁路与上张支线在梅林车站相接与浙赣线相连,可达全国各地,公路与105国道及昌樟高速公路相连,水路在石上码头沿赣江上可达樟树、赣州等地,下至南昌、九江等地,交通十分便利。矿区内煤矿井瓦斯分布垂直分带平面分区的特征比较明显。影响矿区瓦斯赋存的主要地质因素是煤化作用程度、地质构造、含煤地层岩性、煤层埋深、水文地质条件、煤层厚度、剥蚀强度等 关键词：瓦斯，瓦斯地质规律，尚庄煤矿，地质因素 GAS GEOLOGY RULE RESEARCH ATSHANGZHUANG COAL MINE OF FENGCHENG JIANGXI ABSTRACT The gas is in the process of geologic evolution history of coal formation in the gas geologicalmass. The gas as gas, both its own physical and chemical properties, and because it was born in coal seams and stored in coal seam, so by the geological evolution control. Different coalbearing strata, different coal seam exist own gas geology rule. Reveals gas geology rule, it reveals gas occurrence distribution of zoning, zoning laws, etc, also reveals the gas of hazard formative mechanism. ShangZhuang coal is located in jiangxi province FengChengShi northwest ShangZhuang neighborhood office from FengChengShi territory, eight kilometers, is apart from the capital city of nanchang 60 kilometers. Ore with zhang extensions in railway station in merlin were connected with, can reach depending on all over the country, roads and no.105 and dehydroisophytol highway connected, chang in stone dock along the waterways of ganjiang camphor trees and ganzhou on down to, nanchang, jiujiang, etc, the traffic is very convenient. In the coal mine gas distribution vertical zoning plane zoning features more apparent. Influence of the main geological mining gas occurrence carbonificated role factor is, degree of geological structure, coal-bearing strata lithology, coal buried depth, hydrology geology condition, coal thickness, erosion strength etc. KEYWORDS: gas,gas,geology rule,shangzhuang coal mine ,geological factors 目录 摘要(中文) …………………………………………………………………………………Ⅰ 摘要(
