Abstract: The present disclosure relates to a grouting material for reinforcement of coal-rock mass in low-temperature mining. The material includes a component A and a component B, where the component A includes 100 parts of a polyether polyol A and 0.05 parts to 0.1 parts of a catalyst; the component B includes 18 parts to 24 parts of a polyether polyol B, 21 parts to 26 parts of a flame retardant, 50 parts to 61 parts of polyisocyanate, and 0.05 parts of the catalyst. A preparation method of the grouting material includes the following steps: stirring the polyether polyol A and the catalyst to obtain the component A; drying the polyether polyol B and mixing with the polyisocyanate and the catalyst, and conducting a reaction to obtain an isocyanate prepolymer; adding the flame retardant to the isocyanate prepolymer, and adjusting a viscosity to obtain the component B.

Abstract: The disclosure discloses a method and apparatus for detecting cheat on web page views. The method for detecting cheat on web page views includes that: the page views of a target web page is acquired; it is judged whether the page views satisfies a predetermined condition; if the page views satisfies the predetermined condition, visit source information of the target web page is acquired; and according to the visit source information, it is judged whether the page views of the target web page is cheated. By judging whether the acquired page views of the target web page satisfies the predetermined condition, when the page views satisfies the predetermined condition, it is determined that the page views of the target web page is cheated. By means of the disclosure, the problem of inaccurate identification of cheat on the page views of the web page is solved, thereby achieving an effect of accurately identifying the cheat on the page views of the target web page.
