受限于资源条件和技术水平等因素,长期以来我国形成了大量残留煤资源。对1949~2014年期间国内残留煤的资源量进行了估算,并对其分布情况、赋存条件和煤质等进行了预测。根据成因和特点,将我国残留煤资源可划分为“三下”残留煤资源、薄煤层残留煤资源、保护性煤柱残留煤资源、因条件复杂而无法开采的残留煤资源和采空区残留煤资源等五种类型。1949~2014年期间,我国累计生产煤炭666.19亿 t(不含港、澳、台),露天和井工开采分别占6.47%和93.53%。经估算,我国当前的残留煤资源总量达1390.80亿 t,其中99.45%(1383.19亿 t)由井工开采形成,各类煤矿的资源平均采出率仅为32.39%。我国残留煤资源在华北地区分布最多(38.86%),主要位于800 m 以浅区域(85.50%),且以烟煤为主(76.23%)。
受限于資源條件和技術水平等因素,長期以來我國形成瞭大量殘留煤資源。對1949~2014年期間國內殘留煤的資源量進行瞭估算,併對其分佈情況、賦存條件和煤質等進行瞭預測。根據成因和特點,將我國殘留煤資源可劃分為“三下”殘留煤資源、薄煤層殘留煤資源、保護性煤柱殘留煤資源、因條件複雜而無法開採的殘留煤資源和採空區殘留煤資源等五種類型。1949~2014年期間,我國纍計生產煤炭666.19億 t(不含港、澳、檯),露天和井工開採分彆佔6.47%和93.53%。經估算,我國噹前的殘留煤資源總量達1390.80億 t,其中99.45%(1383.19億 t)由井工開採形成,各類煤礦的資源平均採齣率僅為32.39%。我國殘留煤資源在華北地區分佈最多(38.86%),主要位于800 m 以淺區域(85.50%),且以煙煤為主(76.23%)。

Due to the factors of resource conditions and technical level,a large number of residual coal resources have been remained during the past several decades in China.We estimated the residual coal reserves which had been detained from 1 949 to 2014 in China,and predicted the distribution,occurrence conditions and coal properties of these resources.According to the causes and characteristics,residual coal resources are divided into five types:“under three”resources,thin seam,protective coal pillar,resources unable to be exploited with complex conditions,goaf.Between 1 949 and 2014,Chinese had cumulatively produced 66.62 billion tons of coal,not including Hong Kong,Macao and Taiwan,in which the output of open-pit and underground mining occupy 6.47% and 93.53%,respectively.Furthermore,We estimated the current residual coal reserves of China,which had achieved 139.08 billion tons,whose 99.45% (138.32 billion tons )were formed from the remains of underground mining,and the average recovery rate of resources for all types of coal mines was only 32.39%.The residual coal resources are most distributed in north China (38.86%),mainly located in the buried depth area less than 800 m (85.50%),and primarily bituminous (76.23%).
