Not illustrated. 1913 edition. Excerpt: ...and Mining Company was nearly 167,000 tons, and that taken out by numerous other mines would be at least equal to that sum. Thus the total amount mined in that year would not be less than 300,000 tons. The coal mined in the Ch'i-t'o-li, Yiian-k'ou-tien, Men-t'ou-kou, and Chai-t'ang districts is almost all sent to the Pe-king market, the total amount being 178,950 tons. In Mei-ling the coal-bearing formation forms a syncline, imbedding six coal-seams, of which the thickest has a thickness of ten feet. In Ch'ang-k'ou-yii the thickness of the coal-seams varies from one foot to thirty feet. The formation extends thence toward the east, occupying a wide area, and forming a syncline. The strata are much disturbed and the inclination is rather steep. The quality of the coal is also very variable in different places, so that until further exploitation supplies more detailed information it is not possible to tell whether the coal mined in different places belongs to the same bed or not. Generally the coal is non-caking and burns with a short flame. The average result of technical analyses of it together with those given by Mr. Drake is as follows: CHING-HSING COAL-FIELD Ching-hsing-hsien lies on the highway leading from Chih-li-sheng to Shansi-sheng, and is connected by railway with Cheng-t'ing-fu and T'ai-yiien-fu. The Hung-chien colliery is situated about 16 km. north-east of the town, and the Huan-kou colliery about 2 km. south-west of it, both being worked according Ching Hsing Coafiei r2. to European methods. Be sides these there are many small mines, scattered over an area about 40 km. across, with Ching-hsing as its cen-tre; Pei-hsing, Nan-hsing, Pai-piao and Shun-tao-ti to the north, and Hung-an and Pan-ch'iao to the west and...show more
