Hung-fat, director of Shanxi Province Economic and Trade Bureau, the provincial government leadership has repeatedly stressed that the requirements of the province's power plants can no longer take the main source of electricity supply pressure at the local small coal kiln, the quality of the local small coal kiln no guarantee that the supply of instability, although a certain degree of price advantage, but said变就变is not conducive to security and stability of plant production, with the coal industry in our province to implement three major strategies of small coal mines and the implementation of resource integration, requested the power enterprises to adjust the coal supply structure as soon as possible, we must allow for large coal mines to account for more than 50%.

据山西省经委主任洪发科介绍，省政府领导多次强调，要求省内的电厂再不能把电煤供应的主要来源压在地方小窑煤上，地方小窑煤质量没保证、供应不稳定，虽有一定的价格优势，但说变就变，不利于电厂的安全稳定生产，随着我省煤炭行业实施三大战略，对小煤矿实施资源整合，要求电力企业要尽快调整煤炭供应结构，一定要让大矿供的煤能够占到50%以上。

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。

It is important to reduce the span of the hard roof to avoid its impact load on supports. However, at longwall top coal caving face, the periodical weight of roof is a main factor that crushes the top coal, which is beneficial to the top coal recovery. How to use the roof pressure safely is of crucial importance in top coal caving. Based on field monitoring, theoretical analysis of strata movement, the numerical model of compound structure of hard roof stepped cantilever and the top coal cantilever beam is built, and the parameters of the model are also determined. The elasto-plastic finite element method is used to analyze the effect of hard coal fracture under the abutment pressure of hard roof, and the cracking coefficient is defined according to the stress state of the element.

通过对岩层移动的现场观测，建立了&两硬&条件综放采场台阶悬臂—悬臂梁组合的煤岩组合结构力学模型，并以此煤岩结构为基础，建立&两硬&条件综放采场顶煤压裂的有限元数值模型，分析了坚硬顶板不同来压步距对坚硬顶煤的压裂效应，并确定了合理的支架阻力，从而对坚硬顶板进行有效的控制，消除坚硬项板对采场的冲击隐患，同时保证采场矿压对坚硬顶煤的有效压裂，达到提高顶煤回收率之目的，由此形成了坚硬顶煤、坚硬顶板条件下综放采场围岩控制的基本理论和方法。
