      This article was written on the bases of observation data obtained from the course of several years of strata movement at the Fushun mining area. By making use of the method of interrelation analysis and the prineiple of least square method, linear equa-tions of displacement angle, border angle, fracture angle and maximum angle of draw in relation to dip of coal seams, under conditions of sand-flushing method for inclined seams of particularly great thickness have been derived. These equations for calculating the above mentioned angles may be referred to in planning out new mining areas with the same or similar geological and mining conditions.

      本文是根據撫順礦區多年來的巖層移動觀測資料編寫的.用相關分析的方法和最小二乘法原理,解出了在傾斜特厚煤層水砂充填開采條件下的下山巖層移動角、邊緣角、破壞角和最大下沉角與煤層傾角的線性方程式. 求算這些角值的方程式,可供在相同地質采礦條件下或類似此條件的新礦區參考.

      The weighted rod boring method introduced in this essay is a new trial. It has been proved by theoretical and practical studies that the results are better than those employing ordinary 68-milimeter stabilizers. The author's experiences of using weigh ted-rod boring with-out reinforced bits in Peipiao Coalfield show that better effects are obtained both as to the hourly efficiency and to the prevention of borehole devia-tion. It is recommended as a reference to whoever deal with geological exploration.

      本文介紹的加重管鉆進法是一個新的嘗試,且通過理論與實際的研究都證明較采用φ68毫米鉆鋌為優.作者在北票煤田采用的加重管與肋骨鉆頭鉆進的經驗表明,無論從時效還是從防止孔斜方面都獲得較好效果.可供有關勘探工作人員參考使用.

      As production increases, gas emission in a mine gradually increases, and also may accompany with the sudden bursting of coal and gas. For a new coal field, it is neces-sary to make preliminary estimate, so that precautionary measures may be adapted before gas emmission.Formerly, preliminary estimate of gas emmission in a new field was based upon emmission quantity as proportional to working depth More recently, some one also proposed that at certain depth, gas emmission will reach a limiting value.

      As production increases, gas emission in a mine gradually increases, and also may accompany with the sudden bursting of coal and gas. For a new coal field, it is neces-sary to make preliminary estimate, so that precautionary measures may be adapted before gas emmission.Formerly, preliminary estimate of gas emmission in a new field was based upon emmission quantity as proportional to working depth More recently, some one also proposed that at certain depth, gas emmission will reach a limiting value. These view points, however, are only suitable in geological condition of coal seam in identical fie-lds. In pratice, it is customary to meet complex coal seam with geological changes,which influences the gas emmission greatly. Hense it is necessary to consider the amount of gas emmission with respect to changes of space and time as the composite influence of all these factors.Article also recommends that in mine production, a detailed account on the quan-tity of gas emission should be made in relation with all factors qualitatively and quantitatively. Thus, basing upon such relations and the actual condition of new coal field, the gas estimate may be made.

      在生產發展中,礦井瓦斯涌出量大大增加,并伴隨產生煤和瓦斯突出.進行新區瓦斯預測,把預防瓦斯工作做在瓦斯未發生之前,就非常必要.以往預測新區瓦斯涌出量,是把瓦斯與開采深度看成正比關系進行的.最近,又有人提出在一定深度處瓦斯將達到極限值.以上看法只適合于煤層地質條件完全相同的地區.實際生產中經常碰上復雜的煤層地質變化,這種變化對瓦斯涌出量影響很大.因此,應該把瓦斯涌出量在空間和時間上的多變性,看成是各種因素綜合影響的結果.本文介紹在生產中,應用統計方法找出瓦斯涌出量與各影響因素的定性定量關系,根據這種關系和新區條件,進行瓦斯預測.
