根据内蒙古乌达矿区高硫煤9煤层（有机硫同位素值 d 34 S=－12.3‰~5.8‰，黄铁矿硫同位素值 d 34 S=－18.7‰~1.1‰）和低硫煤13煤层（有机硫同位素值 d 34 S 为8.9‰~ 11.5‰，黄铁矿硫同位素值 d 34 S 为8.3‰~ 9.7‰）剖面上有机硫和黄铁矿硫同位素的组成，结合煤岩学特征的综合分析以及黄铁矿化菌落和蓝藻胶壳的发现，提出了高硫煤中硫的演化模式，认为高硫煤中硫的同位素由于硫酸盐的异化细菌还原作用导致硫同位素大规模分馏，使之趋于负值。

At the time, Heilongjiang owns the industrial foundation of building industrial cluster and the advantages in natural resources. Ander the economic globalization background, Heilongjiang should make use of the policy of developing vigorously of the country, seize the finest hour that estate changes at home and abroad, cultivate an array of competitive equipment、petroleum and chemical coal、green food industrial clusters and a batch of high and new technology、new industry having the lurking competitive edge cluster actively. To develop a fine environment for Heilongjiang building industrial clusters,accelerating vitalizes.

Based on the circular oxidation self-combustion mechanism of high-sulphur coal , the inhibition mechanism of Ca2 to high-sulphur coal is explained from chemical, negative-catalytic and physical inhibition actions.

在实验室实验的基础上，分析了混有不同浓度氢氧化钙煤样的氧化升温梯度和阻化时间变化率，基于高硫煤的循环氧化自燃机理，从化学反应理论、负催化活化中心理论和物理阻化作用三个方面深入分析了氢氧化钙阻化液对高硫煤的阻化机理。

The results indicate the mutual effect exists between the single coals, which could increase the maximum of thermal weight loss obviously and has a small effect on the temperature extent of the weight loss. The main pyrolysis production of coal is coke, but the main production of waste plastics is tar; the yield of water became decrease and the gas became increase by adding the waste plastics. And the CRI and CSR decreased with the ratio of waste plastics in coal. The main ingredients of tar from blend coal are aromatic hydrocarbon and alkane, while those of waste plastics are alkane and alkene. The result of co-coking with coal and waste plastics make the light tar and the aromatic hydrocarbon increase obviously. The combustible ingredient(CO、H2、CH4) of gas from co-coking with coal increase at different ratio; Co-coking with coal and waste plastics could increase the combustible ingredient and thermal value of gas.

结果表明，废塑料与煤混合物在煤的塑性温度区间内存在明显的相互作用，使最大热解失重峰迁移，热解速率变大，且随着废塑料配比的增加呈现规律性的变化；煤热解产物固体焦炭为主，而废塑料的热解产物以焦油为主，废塑料的添加使得总体焦炭和水产率下降，焦炉煤气和焦油的产率增加，即共焦化呈现出明显的&增油减水&效应；随着塑料添加量的增加，焦炭热强度呈现劣化趋势；废塑料代替瘦煤配煤炼焦可使其比例提高到3%而不影响焦炭的质量；纯煤焦化所得焦油以芳香烃类和烷烃类为主，而废塑料热解焦油以烷烃和烯烃为主；废塑料配煤炼焦，可使得的焦油呈现&环构化&和&轻质化&趋势；废塑料的添加可使煤气中的可燃组分(CO、H2、CH4)的含量均有不同程度的增加；废塑料配煤炼焦可以优化焦炉煤气的组成，增加煤气中的可燃组分，提高焦炉煤气的热值。
