Abstract
The invention relates to an ammonium nitrate explosive for coal mines and a preparation method thereof. The invention is characterized in that: the ammonium nitrate explosive is prepared from the following raw materials in part by weight: 60 to 78 parts of ammonium nitrate, 5 parts of liquid paraffin, 8 to 18 parts of stalk powder and 8 to 20 parts of potassium chlorate; and the preparation method comprises the following steps of: weighing the raw materials, drying, mixing, drying and the like. The invention has the advantages that: the stalk powder instead of wood powder is fully utilized, resources are saved, a proportion in processing strictly meets the requirement, and a problem of nonuniform proportion is avoided; and table salt is taken as a smoke suppressor to solve the problem of water adsorption.
Description
Technical field
The present invention relates to the method for a kind of colliery with ammoniumnitrate explosives and preparation thereof
Background technology
Ammoniumnitrate explosives of the prior art, mainly by ammonium nitrate as explosive oxidizer, adopt wood powder to play the effect that moment detonates, as smoke suppressor, but in the concrete process of using, there is following problem: no matter be wood powder or wood charcoal powder with salt, all be to get by the timber preparation, cause the waste of resource, and in processing, occur the phenomenon of proportioning inequality easily; When adopting salt, because the moisture in the easy absorbed air of salt, so effect is undesirable.
Summary of the invention
For overcoming the defective of prior art, the invention provides a kind of colliery with ammoniumnitrate explosives and preparation method thereof, to solve the wasting of resources that prior art exists, the uneven and unfavorable problem of effect of processing proportioning.Technical scheme of the present invention is: a kind of colliery ammoniumnitrate explosives, it is characterized in that, and form by the raw material of following weight part: ammonium nitrate 60-78 part, 5 parts of whiterusss, straw powder 8-18 part, Potcrate 8-20 part.
A kind of method for preparing the described a kind of colliery of claim 1 with ammoniumnitrate explosives is characterized in that, may further comprise the steps:
(1) takes by weighing each raw material of above-mentioned weight part;
(2) straw powder is carried out drying, and cross 60 orders with top sieve;
(3) above-mentioned each raw material is mixed heating;
(4) mixture is cooled off;
(5) packing.
The Heating temperature of described step (2) is 100 ℃-110 ℃, and be 30 minutes heat-up time.
Advantage of the present invention is: made full use of stalk and replaced wood powder, saved resource, and made the proportioning that adds man-hour in strict accordance with requiring, the problem of proportioning inequality can not occur; Adopt salt as smoke suppressor, solved the problem of adsorption moisture.
