Water-coal slurry additive: Made from petroleum sulphonate, this product with a low price and good performance can be used to produce water-coal slurry in the factory. The rheology, stability and burning performance of the water-coal slurry made from it are much better. It has a good benefit and a wide market prospect.

水煤浆添加剂：以石油磺酸盐制得；该产品价廉性优，可用于各水煤浆厂制浆，且制得的水煤浆流变性、稳定性和燃烧性能较好；效益明显，市场前景广阔。

The second group are the mixtures of Jurassic coal-formed oils and Cretaceous-derived oils. The carbon isotope, n-alkanes and isoprenoids compositions of these oils are similar to core extracts from Jurassic coal measures. However, sterane and terpane compositions of these oils show affinity to Cretaceous source rocks. It is deduced that coal-formed oils dissolved the biomarker-rich Cretaceous bitumen of relatively low thermal maturity, and overprinting occurs during oil migration.

第二类原油具有侏罗系煤系烃源岩与白垩系湖相泥质烃源岩混源的特点，这类原油的碳同位素组成、正构烷烃分布特征和姥植比等均表现出煤成油的特征，但甾、萜烷烃类化合物组成与白垩系烃源岩接近，推测是由于侏罗系煤成油在向上运移成藏过程中，受到成熟度相对较低、生物标志物相对丰富的白垩系烃源岩的浸析作用所致。

It is a new way of direct utilization of coal aromatic macromolecule structure without the thermochemic conversion of coal. A coal filled polyolefin master batch has been developed.

直接利用煤的网状大分子结构，开发不经或少经热化学转化而直接利用的煤填充高分子复合材料新技术，是煤清洁、高效利用的新途径。

This article tries to summarize experiences of the small collieries in mining shallow coal seam in north of Shanxi Province, and suggests to reform unadvanced mining of room and pillar to longwall remaining coal pillars support mining which can largely inprove the coal recovery rate.

在总结陕北煤田小煤矿开采浅部煤层经验的基础上，建议将落后的房柱式改革为长壁留煤柱支撑法开采，以较大幅度提高采出率。

And then we do many experiments about using different fineness of unblended coal and coal blending to coking,and get some results of the effects of coal fineness on coke strength to provide a reliable reference for coking production.

根据我厂一、二炼焦用煤的细度不一，焦炭质量有明显的差别，进行了单种煤和配合煤不同细度的炼焦试验，了解不同细度煤对焦炭强度的影响，为炼焦生产提供可靠的参考依据。

It is clear that the coal combustion efficiency is significantly reduced if uncombustible material is dryly mixed with pulverized coal and the more the uncombustible material added the lower the coal combustion efficiency is.

试验表明，简单采用干粉混合的方法添加不可燃粉料恶化了煤粉的燃烧条件，随添加量增加影响加剧。添加粉料中，白云石粉对煤粉燃烧率影响最大。

In order to solve the safe mining question of the coal seam unmined which is in the second level in Xiaonan coal mine, took the No. 14 coal seam as an example and analysed the geologic agent systematically which influence the gas hosting.
